@NovaSquirrel software blitting on a 65c16... ouch, yeah, it'd be a miracle to have CPU time for anything else
@elfi It was directly Blue Sphere inspired and you have to collect all of the hearts, which turn into harmful skulls when you touch them.
It's just a copy that skips transparent pixels, which any processor ought to do well at. The non-aligned version was a little more complicated but still not too bad.
It's just really bad when I have to do it a ton of times per frame instead of like three at the most haha.
@NovaSquirrel also watching these had me whistling the blue sphere theme under my breath fdsghaj
