This is like any other platformer. Use the right & left arrow keys to move, the up arrow key to jump, and the down arrow key to duck. Avoid the spikes. The yellow square is a bouncy. The bouncy makes you jump. Try to get to the right end of the screen. This game also includes a boss battle. It is at level 11. At the boss battle, Jump on the mini monkeys. When the banana monkeys come, jump on them but avoid their banana.
