I have a soft spot for TD games, but I really liked this. Different types of enemies were pretty cool, and the main mechanic of powering the tower was unique. The early part of the game was a little rough with how slow the character is, but by the end it was fun to have gotten all of the upgrades. I'd like to see the game adjusted to be a little faster, personally, but overall you did really well.
I managed to finish the game with a score of 6381!
