The Game is a cool puzzle-platformer game
I like the puzzles and the way you cant cheat your way by dropping to the hole and respawning(if the button is far away and the spike is behind a door next to the spawn). Also good is that getting hit by enemies actually matters and it makes the game into a puzzle like game.
I couldnt play further than level 7 because i couldnt jump, but the other levels are good too.
I also found out that in level 5 or 6 (the level where you could push the button at the spawn and open the door next to you), that you could get on the door when it goes up, which could make for more vertical levels, or secret ways(1 way where you can platform and 1 way where you could jump from on the door)
