I'm sorry you didn't get this uploaded in time. You made a great game! The UI is gorgeous, I like your twist on the usual kind of click the enemies game, going back to the tree to restore mana is a really nice touch.
One thing I think would take this to the next level is some powerups that scale the player out of control so you're just slaughtering enemies and exploding them in AOE.
Amazing game! I'm sure you would have placed really well had you been able to submit on time.
