The gap
A platformer lives or dies by its jump feel, and every new level needs proof that it can be finished.
Game templates

The gap
A platformer lives or dies by its jump feel, and every new level needs proof that it can be finished.
What it is
This template ships tuned physics, levels you edit as text and a bot that plays them with the real physics to show they are beatable.
How you use it
Unzip, serve the folder and open index.html, then edit game.js; npm test plays it again in headless Chrome.
Source code of a real, playable game to reskin and learn from, with a smoke test whose bot plays it.
Use it when
Built for
Each level is a list of strings: # ground, - thin platform, ^ spikes, o coin, * gem, S spring, C checkpoint, M W V moving platforms, e h b enemies, F fake wall and G goal.
Every few frames the bot tries dozens of short input sequences with the real step function and keeps the one that brings it closest to the goal on a route map, never dying and always landing.
Plain JavaScript and Canvas 2D; open index.html through any static server and edit game.js.
A headless Chrome test loads the game, checks the console, presses keys and taps, and lets the built-in bot play a run to its result screen.
