Trampoline

Bounce higher and higher. Hold to press the mat down, let go at the bottom for the big push, and never lean on the way up. Ten bounces; the highest one is your score.

Draft. It is built, compiled and tested like every other game, and it is not on the hub: "draft": true in build/games.json keeps it off the cards, out of the sitemap and without a readme page until the rules are real. Take the flag off when it is worth playing.

How it is put together

tramp.ts is the rules and touches nothing - no canvas, no engine, no storage. trampoline.ts is everything that draws or listens. The split is what makes the hard half testable: node test-tramp.js runs against the shipped, minified JavaScript rather than the source, which is how a minification fault gets caught.

Every screen except the run itself belongs to the shared shell, so this game has one scene of its own, play. The menu, the pause card, the game-over screen and the high-score table come from src/shared/scenes.ts and look and behave the same here as in the other twenty.

Still to do

• [ ] the actual rules, in src/trampoline/tramp.ts
• [ ] tests for them, replacing the placeholder scoring ones
• [ ] the drawing, in HUD.draw
• [ ] a real favicon and palette
• [ ] take "draft": true off the entry in build/games.json
