You control a robot with the ability to build turrets in CannoDash, a tower defense game where enemies appear from each side of the screen in turn and will chase you down relentlessly. Tanks which hit a turret will get stuck to it until either one is destroyed, but paper planes have no such limitations by travelling through air.

The W, A, S and D keys are used to move the robot around the room. Placing a turret with the enter key deducts ten points from your money counter, but you earn back half of that for every enemy tank or plane destroyed.

There are also two difficulty settings to choose from, and players can beat the game by surviving all fourteen waves without letting any of the enemy units touch the robot. (source: 0stage)
