There is a games jam going on called FloppyJam, where the goal is to create a game that's smaller than a floppy disk (1.44 MB). My usual dev approach could not get a game in anyway that small so I decided the next best option... build my own engine using the command prompt.
The end result is a survive as long as possible shooter in a pinball environment, where your only source of movement is shooting or using the flippers.
Unfortunately this is strictly a windows game as it uses the Windows Command Prompt, I don't have any functional support for the Linux Terminal. But if you do have a Windows machine, feel free to give it a go!
