Great job on the world design - gameplay needs some work, as I didn't notice anything to do besides go around picking up exp shards (or whatever you want to call them). Combat doesn't seem fully functional, as attacking the shadow enemies doesn't seem to do a whole lot and they will just sit there wailing on you until you die (and they move at the same speed as the player, so they will keep following you until you find a ledge or something else they can't bypass). It's a great start though, and gives you something to build on.
