Sprout Quest gameplay: the title, a sword fight, chopping a tree, mining crystal, and the Emberwyrm boss

## How it was built ### Release day: a playable game from a handful of prompts (0.1.0) The first version was built in one conversation on release day, and was a complete, playable game by the first push: a prologue, four areas, real-time battles, guardian bosses, a village to rebuild and gear to craft. Measured from the Claude Code session log, up to that first push: | | | | --- | --- | | Human prompts to build the game end to end | **11** (plus 3 more to set up GitHub and this repo) | | Wall-clock time | ~4 h 25 min, from first prompt to published repo | | Model calls | ~230 | | Tool calls (shell commands, file edits, Blender renders, headless browser tests…) | ~245 | | Output tokens | ~565K | | Input tokens | ~99M total: ~450 uncached + ~716K cache writes + ~98.4M cache reads (the conversation is re-read from cache on every call) | The prompts, roughly: *make a cute mobile adventure game with a fight → level → craft loop* · *use Bun* · *give me a link to play it* · *fix clipped menu text* · *install Blender and make cute 3D art; make weapons feel different and powerful* · *add story, bosses and milestones that gate progression* · *make the first-time experience less overwhelming* · *start with a prologue before the village* · *move the bag near the thumbs* · *let me close the menu from the bottom* · *fix two bugs with the forge quest*. ### Since then: playing it and iterating (0.2.0 onward) Since the first release, development has been a loop: play the game on a phone, describe what feels off, and have Opus 5.5 rework it. Some of the bigger rounds so far: - **Progression overhaul (0.2.0):** a new area, woodcutting and mining with tool tiers, four weapon classes with monster and ore tracks, weapon handling, stamina, level-up screens and gear that stays a mystery until you reach its level - **Playtest data:** an in-game play report (fights, stamina, deaths, time per area) exported after a playthrough and handed back to Opus 5.5 to tune the balance against real play, not just the balance model - **Engineering:** splitting the largest modules, an end-to-end browser test, CI, a `dev` → `main` release flow and in-game patch notes - **Visual pass (0.2.1):** a sharper,
