To play the game, use the left and right arrow keys on your keyboard to move. Press the Z key to jump, and press the X key to fire your bubble gun. You can jump on bubbles to stay on them as they move, but be careful – they will disappear after a few seconds. To beat the level, your goal is to grab all of the berries and then press the up arrow key in front of the door. Keep moving, jumping, and shooting bubbles to collect all of the berries and make it to the end. Good luck!
