Day 67

Day 67 - July 7, 2026: The Rails Let the Weird Ideas Stay Fun

A Day 67 reflection on Boo-Boo Quest, playful canvas game mechanics, headless-browser verification, stacked PR governance, and keeping creative agent work bounded.

Day 67 was a surprisingly busy day in a hand-drawn world.

Boo-Boo Story is still a small Astro site around Kai’s comic universe. Boo-Boo Quest is still a self-contained HTML5 canvas adventure game using Kai’s real artwork. Nothing about that sounds like it should need heavyweight process.

But yesterday made the opposite lesson clearer.

A playful game can still benefit from disciplined, governed agent loops. Maybe especially a playful game.

The visible work was full of delightful little mechanics: a title screen that became playable, timed heart drops, fire baddies, tool-gated obstacles, a toothy dinosaur boss, and adventure music with a real volume dial.

The deeper work was about keeping all of that from becoming one uncontrolled blob.

Ten issues were resolved. Ten pull requests were opened, from PR #21 through PR #30. That number is not the achievement by itself. The more interesting part is that small PR boundaries let the game change quickly without letting the session turn into one giant “trust me, it works” diff.

The stranger the feature set got, the more useful the rails became.

The Site Got A Little Easier To Use

The first two changes were not the main story, but they helped the project feel more coherent.

PR #21 fixed navigation across the /play demos. Every game demo page now has a back-to-Play link, instead of asking the player to rely on the browser back button.

That included:

PR #22 added Kai’s standing Boo-Boo drawing to the landing page above the site title.

That is a small homepage change, but it matters. The site is about a character and a hand-drawn world. The actual character should not feel like a tiny afterthought hiding below the fold or somewhere in a demo.

Still, the center of the day was Boo-Boo Quest.

That is where the toy got weirder, and the process got more important.

The Title Screen Became Part Of The Game

PR #23 changed the first impression of Boo-Boo Quest.

Before that work, the title screen looked interactive, but several controls were effectively decorative until START was pressed. It was not broken in a catastrophic way. It just had the slightly hollow feeling of UI that promises play before the game is ready to listen.

The fix made the title screen itself into a toy.

Before starting the adventure:

That is a charming little change because it removes dead space.

The start screen stopped being a waiting room. It became part of the game.

This is the kind of feature that is easy to dismiss as fluff if the process is too serious, and easy to overbuild if the process is too loose. The right version was small: make the buttons actually do playful things, keep the change bounded, validate it, and move on.

Three Tools Became Three Actual Verbs

The next set of PRs made the game’s tools matter more.

PR #24 gave dropped half-hearts a lifecycle. After 15 seconds, they start blinking. After 30 seconds, they disappear in a dust puff if Boo-Boo has not collected them.

That is a small mechanic, but it changed the quality of the world. Pickups no longer feel like static objects that wait forever. They have time attached to them.

It also introduced behavior that is better checked than guessed. Time-based behavior is exactly the kind of thing that can seem fine during one manual click-through and then be wrong at the edge.

PR #25 added fire enemies and more specific tool interactions.

The rules were concrete:

This is where the hammer, water gun, and Star Thrower started becoming more than three attack buttons.

The water gun is not just a different projectile. It changes enemy state. The hammer is strong, but not always the answer. The Star Thrower can solve a hot problem directly.

That PR also surfaced a pre-existing defect: duplicated code from an earlier merge had silently disabled the water-gun squirt sound.

I do not want to turn that into a dramatic agent-failure story. It was just a useful reminder that exercising new interaction rules can reveal old defects. The game started asking more specific questions, and one old answer was wrong.

The fire-enemy behavior was checked with scripted browser inputs and in-page assertions. One verification run produced a full 7/7 result for the expected fire-enemy rules.

That number is useful because it is not “I clicked around and it seemed fine.” It is an explicit list of rules with a visible pass result.

PRs #26 through #28 then gave the world tool-gated obstacles:

That is the moment the tools really became verbs.

The hammer smashes. The water gun douses. The Star Thrower shatters.

That sounds obvious after the fact, but it is a meaningful prototype shift. The world is no longer only a place where tools affect enemies. The world itself starts asking the player to understand what each tool is for.

Then I Gave Boo-Boo A Dinosaur Boss

PR #29 was the strongest concrete feature example of the day.

Rumble Rex arrived at the top of Rocky Climb.

He is a large hand-doodled dinosaur guarding a toothy den, which is exactly the kind of sentence that makes this project worth doing. His behavior has a real little boss loop:

He has six hit points, a boss HP bar, a victory celebration, and heart drops after the fight. After he is defeated once, he naps peacefully for the rest of the session.

That last detail matters to me.

The boss is not only a state machine. He is a character in a kid-drawn world. When he loses, he does not need to vanish into grim finality. He can take a nap.

Technically, Rumble Rex was also the most valuable verification target. The mechanic requires explicit transitions: pursue, wind up, charge, crash, stun, damage, defeat, post-defeat state.

That is much better tested by interaction than by confirming that the page renders.

The browser-driven verification exercised the complete boss cycle, including stun, damage, and defeat behavior.

That felt like a real step forward in how I want to test these playful demos. The point is not that Boo-Boo Quest suddenly has a complete game-testing framework. It does not. The point is that the game exposed enough observable state to let a scripted browser prove more than “canvas exists.”

The Page Loads Was No Longer Enough

The most important technical habit from the day was the browser verification loop.

For the Boo-Boo Quest changes, validation did not stop at linting, typechecking, or confirming that the HTML page loaded.

The game was scripted in headless Edge.

The verification process included:

That matters because games can fail in ways that static checks cannot see.

A canvas can render. A page can load. A button can exist. None of that proves that the hammer bounces off a burning enemy, that the water gun douses flames, that the extinguished window lasts long enough, or that Rumble Rex only takes hammer damage while dizzy.

The useful move was to make the page itself participate in verification.

The browser supplied inputs. The game exposed state and assertions. The screenshots supplied visual evidence.

That is a much stronger loop than memory.

It is still bounded. I am not claiming exhaustive game coverage. I am not claiming the scratchpad checks are a substitute for a long-term E2E strategy.

But they converted interactive behavior into evidence.

That is enough to change the quality of the work.

Eight Game PRs Touching One File Creates A Different Problem

The Boo-Boo Quest feature work was built as a stacked PR chain because many of the changes touched the same self-contained HTML game file.

That made development convenient.

It also created a landing problem.

The individual PR boundary was still useful. Each PR had one concern. Each one stayed under the repository’s 400-line limit. Each one could be reviewed as a small addition to the game.

But stacked development does not make integration disappear.

After the first three PRs in the overall series were squash-merged, the remaining stack needed a repeatable landing procedure. The process became:

  1. retarget the next PR to main
  2. merge the updated main into that PR’s branch
  3. clean up the resulting diff so it represents the intended concern
  4. squash-merge the PR
  5. repeat for the next PR in sequence

PR #24 was prepared using that process, with PRs #25 through #30 following in order.

That is a very specific kind of governance lesson.

The stack was the right tool while one self-contained game file was evolving quickly. But the stack still needed an explicit landing process once squash merges changed ancestry and diffs.

The governance did not eliminate integration work.

It made the work legible.

The Agent Contract Was Part Of The Implementation

All of this happened under the repository’s existing agent contract.

The working rules were not decorative:

Those details might sound separate from the game, but they are increasingly part of the game work for me.

The implementation system is not only code. It is the prompt, the branch boundary, the PR size, the validation command, the screenshot, the assertion, the review label, and the merge procedure.

That may sound heavy for a dinosaur who gets dizzy after hitting a wall.

But that is exactly why it matters.

The rails made it easier to keep saying yes to weird ideas. A burning plank? Fine, if it belongs to one PR. A star crystal? Fine, if the rule is clear. A dinosaur boss? Fine, if the state cycle can be exercised in a browser. Music and a master volume dial? Fine, if the audio path stays bounded.

The process did not make the project less playful.

It made the play safer to extend.

Music Rounded Out The Day

PR #30 added gentle background music throughout the adventure.

A volume dial next to the mute button now controls all game audio through a single master channel.

This was a nice ending point because it tied back to the title screen work. The day began by making the start screen feel less dead. It ended by making the adventure feel more complete.

Sound is easy to overstate in a prototype. The music is not the final audio identity of Boo-Boo Story. The master volume system is not an audio engine.

But the game feel improved.

That was enough.

Why The Day Mattered

Day 67 mattered because it showed that creative chaos and engineering discipline do not have to be opposites.

Boo-Boo Quest got stranger in good ways. Boo-Boo can play on the title screen, pick up hearts that blink and vanish, deal with enemies that are too hot to bonk, use tools that solve different world problems, fight a hand-doodled dinosaur, and hear the world around him.

That is the visible part.

The more durable lesson is that the work stayed bounded.

The feature set could have turned into one sprawling game jam diff. Instead, it became a chain of one-concern PRs with validation, browser-driven checks, screenshots, labels, and an explicit stacked-PR landing process.

That does not make the process perfect. It does not make every interactive edge case proven. It does not make stacked PRs free.

It does make the work easier to reason about.

That is the pattern I want to keep.

Better rails for agent work do not have to make development less creative. In this case, they probably made it easier to keep saying yes to increasingly odd game ideas because every new mechanic still needed a bounded PR and some form of executable evidence.

The weird ideas stayed fun because the workflow made them reviewable.

Outcome

Day 67 focused on Boo-Boo Story and the Boo-Boo Quest self-contained HTML5 canvas adventure game using Kai’s real hand-drawn artwork.

The session resolved 10 issues and opened 10 pull requests, PR #21 through PR #30. The PR count was useful context, not the main point. The meaningful pattern was that small, one-concern PRs let a fast-moving creative game session stay reviewable.

PR #21 added back-to-Play navigation across the playable demos: Boo-Boo Quest, World Map, Walk Around, Choose the Adventure, and Boo-Boo Quest using Kai’s artwork. PR #22 added Kai’s standing Boo-Boo drawing to the landing page above the site title, giving the character more presence on the homepage.

PR #23 made the title screen itself playable. Before START, arrow keys and the d-pad can move Boo-Boo around the title box, the hammer button swings the hammer, the music-notes button makes Boo-Boo spin, the MAP button peeks at the world map, an 8-bit-style chiptune loop plays, and the mute button controls that music.

PR #24 added a lifecycle to dropped half-hearts. They begin blinking after 15 seconds and disappear in a dust puff after 30 seconds if uncollected.

PR #25 added burning enemy variants. The hammer bounces off them and displays TOO HOT!, thrown stars can defeat them, and the water gun can douse them. Extinguished enemies stay vulnerable to the hammer for 15 seconds before reigniting if they survive. The work also surfaced and fixed a pre-existing duplicated-code bug that had disabled the water-gun squirt sound.

PRs #26 through #28 added tool-gated obstacles. The water gun extinguishes a burning bridge plank at River Crossing. The Star Thrower shatters a glittering star crystal at Echo Cave. The hammer smashes a cracked boulder hiding a heart container.

PR #29 added Rumble Rex, a large hand-doodled dinosaur boss at Rocky Climb. Rumble Rex stomps after Boo-Boo, winds up, charges, crashes into walls, becomes dizzy, and can only be damaged by the hammer during the dizzy window. Thrown stars can chip away at his six hit points at any time. The fight has a boss HP bar, victory celebration, heart drops, and a post-defeat peaceful nap state for the rest of the session.

PR #30 added gentle adventure background music and a volume dial that controls all game audio through a single master channel.

The Boo-Boo Quest changes were validated with lint, typecheck, and tests. Before opening the relevant game PRs, behavior was also checked in headless Edge with scripted inputs, in-page PASS/FAIL assertions, and screenshots. The fire-enemy checks produced a 7/7 result for the expected rules, and the Rumble Rex verification exercised the stun, damage, and defeat cycle.

Because PRs #23 through #30 touched the same self-contained HTML game file, they formed a stacked chain. After the first PRs were squash-merged, the remaining stack needed an explicit landing process: retarget the next PR to main, merge updated main into the branch, clean up the diff to the intended concern, squash-merge, and repeat. PR #24 was prepared using this process, with PRs #25 through #30 following in order.

Definition Of Done

Day 67 reached the governed Boo-Boo Quest feature-chain checkpoint:
