In bubble jumper, your mission will be to collect as many stars as possible. Try to avoid being crushed between two colliding bubbles. The stars are present on each bubble and you have to jump your robot from bubble to bubble. Use the arrow keys to move and jump. Power the jump by holding down your up button for some time. Bonus score will be awarded if you complete the level in lesser time and lesser damage as well. There are other red and white bubbles that cause damage and also repel your robot when it gets closer to them. Don't fall in the water, it will cause damage.
