This project seems to expose a bug in the online player--sometimes the projectile will not fire when you choose maximum power. Please download to play properly until the Scratch team fixes the problem. This is a proof-of-concept projectile game. Use the left and right arrow keys to control the angle of the gun, and press space to fire. The longer you hold down the space bar, the more power the shell will have. Press the flag to generate new terrain. You'll need to drag the gun so that it's not touching the ground. You could use this as the basis for a scorched-earth type game with battling tanks in a terrain. Up next: tanks and wind!
