needs a little more work but awsome game over all
like people have said level 3 is so much harder then level 2 but thats not such a bad thing its just either we aren't getting enough souls fast enough or the guys were just to strong, but like someone suggested massing the ice towers was the only way i could win besides that i would add a few more towers (most tower defense games have the basic elements {light, dark, fire, water, earth, most have air too i was surprised there was none here} maybe if the player could set the tower into a different mode or something {like instead of the ice tower shooting water and slowing down their enemies it could go into "mammoth mode" and we could see the mammoth ram forward and perhaps stun their enemy) and maybe a couple of spells instead of just one. My favorite tower was the fire tower but thats just my style "burn, keep burning, and burn some more :D" If you want a couple other ideas contact me.
