click on the brown box on the right to buy towers and place them on the green. click the green start button or space bar to start the round.
you cant see some of the projectiles while their in mid air because I made them go really fast to help bypass the clone limit thingy. I will add upgrades soon but for now this what you got. I will also add a proper round system and more balloons (Bloons) but I'll probably do that after or while I add the upgrades. also thanks to a couple of other amazing scratchers for the sounds and music.
