I may have played a bit too much. Very fun and very chaotic game with great, if complex moving controls.
what starts out as a simple game of shooting bloons with cows, you soon realise the deep and complex intricacies of the game, you can go to a wall and hold down space to do orbital attacks, you can shoot the walls and other cows to ricochet kills, you can spawn in cows into the floor to launch them at high speeds, the possibilities are endless.
I stopped after wave 100 but there is something simply addicting about its simplicity.
