The forward key(W) doesn't work. I still tried playing it using A,D,S and it was a weird experience with that. I don't know how to feel about this game. On one hand it perfectly incorporates the theme in a generic yet good way. I like how you deal less damage if you use too much fire or too much ice.
On the other hand, game lacks visual clarity. I couldn't tell when I was being attacked or when I was attacking. Maybe when you deal some damage a number shows up showing how much damage you have dealt?
