Good start! I included it in my compilation video series of all of the GAMES MADE QUICK??? Games, if you'd like to take a look :)

These tanks look like Roomba™s and I think that makes this game about 7× better.

I love when games keep running after I've died; there's something very soothing about watching my Roomba farm develop, wander around aimlessly, and shoot at nothing.

Also I dig this music, punctuated as it is by the occasional pewpew.
