Pretty ok but I feel like you needed a little more of testing; once you enter the game you cant close the game unless you finish it, cant modify the volume in-game, and I feellike the collisions are too big (you die even if the enemy is not touching you). Also I was searching for a attack button, since the player has a wrench I thought I could attack.
Levels are cool and movement and jump feels nice, good job overall! If you can, I recomend you from now on to update a web version too; people tend to try it more if it can be played without downloading anything.
