For the newest #tweettweetjam I made a very basic space shooter (layout inspired by Gyruss/Tempest) in <560 characters. It even includes a bit of sound via poke-ing to the sfx memory, since the jam rules say "code only" without separate gfx/sfx assets.
Use ⬅️/➡️ to move, ❎ to fire.
(I may write up a commented / uncompressed version of the code at some point...)

After the jam I revisited this. The code still fits in two tweets (<560 characters, no sprites), but there's more continuous motion and multiple enemies on screen at a time, though now without SFX:
