Damn, that's cool! Making your own tower be able to attack you... Maybe it's simple, but it turns the gameplay upside down, very clever idea. Two things, that gets me to rate it's "fun" 5 out of 5: first you able to stop your enemies by blocking them - it's hilarious, but it works! And the second, is it just me or you really added sample from "wait a minute who are you" meme video to main music theme?
