This game looks really really good and the controls are smooth. I love the 3d low poly models, the bonfire and magic particles and also the lighting. The effect when you sacrifice is amazing and the animations run smooth, too. After a few waves ( I played till wave 7 ) the game get's a bit boring, because there didn't seem to be any new enemies or upgrades. I quickly figured out how to beat each enemy and the difficulty only increased by the amount of enemies you have to slay, not their difficulty or new mechanics. Because of that the sacrifice was kinda useless to me. Also there are no sounds, except the music, which could have made the atmosphere of the game even greater. The music is also a bit too repetetive and there is a lack of musical resolution. Also I think it sounds very dreamy and calm, which doesn't fit the mood of the game and it has no fade in or fade out, which leads to this loud noise when the music loops. All in all am I nitpicking a bit, but I wanted to give you some feedback, how to improve this awesome looking game :) I really liked it, well done
