You probably already know this game, I made it again just for fun. I tried to make is as small as possible to fit it onto an QR code, but i'm not able to go lower than 11.8kB (for QR code i would need to go as low as 4kB). The game is controlled by arrows, you can hold space to make the game faster. If the snake crashes into itself, the game crashes.
It is written in C using Windows API. I'm going to release the source code soon.
