Interesting game; I like how you give the player a lot of options for customizing their character (stat-wise, at least). The game is far too easy when you're an archer with all the speed perks, though. I just ran in circles shooting at the middle (where all of the enemies congregated) until I had about 4000 points and got bored.
Having said that, the game might be too hard for melee classes, I only played one round with a melee class though so I could be wrong.
You could probably get it sponsored.
