Crank the World: Playdate demo

You know Playdate, the cute yellow console with a crank? I think I saw it in person last year via Inês, and early this year they started to have Lithuania as a shipping destination, so I got one. And then what would I do with it? Of course, try to make a demoscene demo :)
First impressions The device is cute. The SDK is simple and no-nonsense (see docs). I only used the C part of SDK (there’s also Lua, which I did not use).
