This is a 2-player game. Each rocket has 3 HP (health bars at the top). To win the game, deplete your opponent's health to zero. Controls: Player 1 (Yellow) WASD to move, and E to shoot. Player 2 (Green) Arrow keys to move, space to shoot. Power-ups: Heart - when collected, it sets your HP to 3. Bomb - when collected, your opponent's HP decreases by 1. Swapper - when collected, your opponent temporarily increases in size, and you decrease in size. This causes your opponent to be an easier target to shoot.
