You should.

I left it running for a while by accident, and this is how far it got

This I'd love to have as a game feature xD
How'd you manage to break it?

OMG!

Hey shadow,

Read your comment and forgot to reply. It's easy to break - it's a hidden "feature". There's a variable near the top of the code:

CORRUPT_MODE = FALSE

Switch that to TRUE and off you go!

I thought it might be nice to have a glitch monster who pokes random values into core memory -- you have to get out before the level is no longer completable. Although -- there's always the chance it will poke an exit index into the map right in front of you.

Or: a superhero game set in a city riddled with corruption. (wakawaka)

I imagine you could have controlled randomness to make glitchy levels less likely to create things you don't want. Like limit it's range so that it always misses the real exit and doesn't spawn certain things.

Maybe you can make it impossible for the game to spawn a working exit after the level first starts?

This is the code that does it (if corrupt_mode):

for i=1,5 do
poke(rnd(0x8000),rnd(0x100))
end
