Arrow keys to move and aim. Press 1 for pistol, 2 for AR, and 3 for rocket launcher. Press P for shop. The first upgrade makes the bullets go faster. The second upgrade makes the bullets do more damage. And the third makes them do more knockback. (RPG has no upgrade to OP already.) The first set of upgrade is for Pistol, pressing the arrow key on the screen switches it over to AR.
Inspired by my little brother, who made a game similar to this, and the need for a fighting game.
