Great game :D! Good amount of screen shake :D, enemy variety...
Maybe the game would have had more interesting choices if the enemies could hurt each other :). At least for the exploding one.
The big troll with knives is very brutal xD. A little window for invurnability after getting hit might be good :).
Only one bullet is pretty common, but it's good to see a spear, which you can throw light or hard :).
Good luck with this game and with future projects :)!
