So I picked up a small Arduboy on Kickstarter, and I tossed together a game.
It’s cool to be playing with a device with only 2.5K of RAM (of which 1K is dedicated to an offscreen drawing bitmap), and only 32K of program space (of which about 8K or so is dedicated to the Arudboy firmware). The way you write software for such a small device is completely different than how you’d write software for a larger device with more memory.
The game is a variation on the box moving puzzle games out there; at present I have 30 levels of varying difficulty. You can download the sources for the game from GitHub.
