Aim of the game: Find all the toothbrushes in the chests, avoid rocks to stop your lives going down, and grab the Pinky Ponk juice bottles to stop your thirst from going up to 8. If the thirst = 8 or your lives are equal to or less than 0, then it's game over. If you manage to find all toothbrushes and survive then you win the game. Instructions: Arrow keys to go left, right, up and down. Press space near a chest to open it, and press space near the juice bottles to grab them and decrease your thirst.
