This game is cute. I like all the enemies and the main skeleton. The skeleton was missing his torso for me, which I am pretty sure isn't supposed to be the case. The build of the game you distributed throws up the console with all of your debugging output, and several errors. Specifically the errors I saw came when trying to animate going down the ladder. Also spiders spawned inside of walls, but even Minecraft can't get that right so whatever.
Good job
