Make your enemy neighbour farmers explode before time is up. If you win enough rounds, you will win the match. You can get several power ups, for example to increase the radius or damage of your explosions, to drop more barrels, to speed your movement or to get immune to bombing.
Player one / single player: use the arrow keys to move around and the space bar to drop bombs.
Player two: use WASD to move around and the left CTRL to drop bombs.
