Well I didn't create the levels, they're randomly generated :). But thanks!
Yeah, I should have removed the healing from room transitions. I added that for testing, and never removed it...
I agree I should have balanced the losing of keys a bit more. In hindsight, I should probably always remove one of the 3 non-movement keys first, and then randomly, or something like that. I didn't really have enough time to balance things out, sadly.
Thanks for playing, and for playing long enough so that you actually saw most of the things there were to see!
