Pros- interesting game, cool puzzles.
Cons-laggy(even after setting cache to unlimited), annoying control scheme, game gets tedious when the monsters offer no challenge and there are repeated deaths from jumps that either lag or need to be pixel perfect or some combination of both. I understand you want to make a game difficult, but dying 15+ times trying to jump from ladder to ladder and then easily killing any enemies without effort isn't that fun.
2/5. Needs some work.
