Limited Survival

You must avoid the baddies trying to attack you while also staying within the constantly shrinking border. If you touch the border you begin to die. In order to expand the border you must pick up crystals which randomly spawn within the border and bring them to the console in the middle of the screen. You can shoot enemies by aiming with the mouse cursor and holding down left click. However, shooting reduces your movement speed by 40%. You can move using WASD or arrow keys.  Killing enemies earns one points. Bring crystals to the console earns five points.
