good but
I see many people saying this was good because it was challenging but It seemed at some points like the only challenge was that (especially on boss levels) you had to memorize a set path and do it perfectly( the lava boss in particular) which I guess is fine if that's what you are going for. With the way the boss fights are set up tho they don't really feel like a puzzle game (ie 1 or so puzzle elements the rest just up down left right with perfect timing) and don't feel like they fit with the puzzle theme. Other than that most levels were pretty good and the visuals were all nice (rocks and enemies get hung up on edges that arnt there sometimes tho) so good overall.
