Avoid that Mario and Luigi rescue the Princess, throwing those barrels to kill them, moving with the arrow keys and dropping them with the spacebar... The second player moves with the A and D, and go up the stairs with the W.
Play like the classic Pong and avoid the explosives explode on your territory. Be alert and send the grenades to the enemy land. 2 players optional.
INSTRUCTIONS: W,A,S,D and Arrow keys.
