I think you forgot to metion that you used waterflame's -Whatever!- at the beginning stage of the game.
Fun little game, a pretty typical tower defense gameplay wise but with a less common story.
However, I found a glitch that breaks the game immediately. When you pick up your angel and place him on a square he attacks immediately. The cooldown for the attack is not global and will be ignored when you do this. So if you spam click on the square the angel is on he will attack constantly. Might want to fix that as it breaks the game entirely.
Other than that glitch, I found nothing wrong with the game and had a fun time playing it. Nice work.
So, i am god? Heh, heh.
