Holy crap. This game was amazing.
I cant believe you actually got this done in 4 days xD I could play this forever if it wasnt for the fact that after wave 30, my GPU is starting to stutter :p (maybe next steps would be some optimization?) ... Well it only stutters if I try to speed it up... but yea :')
I really love how this game enforces a different strategy compared to other TDs. Well done!
