If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
Robots love stars. The robot’s sole aim is to get as many as he can. The problem is they are attached to giant floating bubbles raising from the sea.
Jump the robot from bubble to bubble, collecting stars on the way, avoiding damage bubbles, repeller bubbles, falling into the sea and bombs.
Use the left and right arrow keys or A and D to move. Hold the up arrow or W to increase your jumping power, and release to jump.
