Each player has an inventory full of items on his side of the screen (Player 1 left, Player 2 right) he wants to empty. In order to achieve this, a player has to catch the item which currently is at the bottom of his inventory (marked with orange color).

Both players sit in the same boat (grey circle).

Player 1 can move the boat with the the keys A and D, player 2 with the left and right arrow. Moving the boat costs the player energy which you can see by looking at the color of the inventory (gmore red => more energy consumed). Players can get new energy by catching items they don’t need.

To catch an item, a player has to press the catch button (S for Player 1, down arrow for player 2) last before the boat touches the item on the game field.
