This game wouldn't be bad, except the rate the character accelerates at is enormous. Then on top of that, you accelerate about 3 times FASTER when your on an ice block. Physics doesn't work that way.
So I think I have found the max DPS build
Fire
3/3 Advanced Fireball
4/4 Hot Air
1/1 Double Fireball
4/4 Rapid Fire
1/1 Triple Fireball
3/3 Pyromancy
Ice
3/3 Winter's Might
1/1 Icebolt
3/3 Frostbite
3/3 Icebolt Frenzy
2/2 Glacial Flow
Then all you have to do is hold the keys for Icebolt and Fireball at the same time and watch things melt.
