If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
In this game, you find a challenging obstacle course. Try to make it through all the levels as fast as you can, avoiding your enemies. Each time you land in a spike pit, touch a little yellow monster or a cannon or when you get shot, you lose a life. And with every life you lose, the pixels get blurrier.
Use the Arrow keys or WASD to move and press Space to shoot. Press P to start the game or to pause it.
