nice short fun game, its always fun to find 'secrets' so to speak as well.
I always preferred up or w in wasd as they're interhchangeable. Space is more for mouse users i'd say. I remember playing spiderman ps1 on PC and I'd use space for jump while using arrow keys cuz its closer, using wasd + space will be a bit tricky as a right-hand user.
thanks for not making a dungeon that makes jumping awkward! This game takes a bit of patience and timing, i like it
