the original idea was bloated (256b) and dumb. then i cut it down to this approach and ended up having bytes left without knowing what to do. because the first collab with kuemmel was some years ago i just hit him up and asked him. so he implemented fitting sound :)
1 key, 1 enemy and 1 life. i guess that is nano enough. you need to match up the color with the enemy before the crash or you are out.

the best way to learn the palette order
ouch. but sound!
I've taken out the sound and pared it down to 128 bytes.
Can I post asm here?
