Red Tanks

Yet another homebrew shooter, but with tanks and pellets! You play as the cerulean tank (blue); your enemy tanks are coral (weak, light red), scarlet (strong, bright red), and crimson (tough, dark red). Your goal is to destroy all the tanks, or remove every pellet in a level. You also have limited ammo, which can be replenished by collecting one pellet, or in later levels, a certain number of pellets.
