Use arrow keys (later I will add WASD) to move around your crosshairs, and spacebar to shoot. R to reload when you run out of ammo (takes 6 seconds!) Click on the orange line to add a "wall" (essentially health) at the cost of 6 points and 2 seconds of not firing. You can add as many walls as you can afford. Basically when you would lose health (from the enemies shooting you) it will first destroy the wall. Enjoy!
Later there will be a full-on shop, but for now I kept it simple. Sorry for any and all bugs. Please comment to me if you find any! KNOWN BUGS: Crosshair target is too big
