use arrows to move (up and down too!), press space to shoot, I recomend having the explosion size about 40 and the speed about 1 for realistic effects. sometimes the game will start and lag alot (usually there are no trees when this happens) if it does, just restart the project.
this is a demo of a game I'm thinking of making, you have to fight enemy tanks and you can buy upgrades (basicly the sliders)
