The game needs a mouse, the game is very hard otherwise. Use the mouse to aim the turret and the arrow keys to move around. The enemies get harder as the game progress. To drop a turret onto the battlefield hit the space bar then klick the turret. The full version klick here. https://scratch.mit.edu/projects/612459651
