@evilpaul_atebit It'd be cool if it showed you which level you're on while you're in the level? Unless that is somewhere and I'm missing it.

I only did the first 8 levels but doing World 2 level 4 in three instructions was very satisfying.

@evilpaul_atebit This gives me 100% but is still showing a handful of red pixels...?

sub #31,r0,r0
sub.mi #-1,r0,r0
mulu r0,r0,r0
sub #31,r1,r1
sub.mi #-1,r1,r1
mulu r1,r1,r1
add r0,r1,r0
sub r0,#981,r0
mov.lt #6,r0
mov.ge #3,r0

@jcreed @evilpaul_atebit Huh! Doubling the resolution? I wouldn't have thought that would make a difference. Very cool!

Looks like anything from 4091 to 4106 works... interesting that it's asymmetrical around 4096, but I guess that makes sense, since it's a curve.

@jcreed @evilpaul_atebit Ah, I see.

And 512 and 2048 work for the next one, which is kinda doing my head in because neither of those are squares, but... cool.
