Arrow keys to move. See how many stars you can get! You can go left and right as well as up and down - you really need to when you get to the boss. End of level trophies: Platinum = 600 stars (possible but SO HARD TO GET!) Gold = 500 stars Silver = 400 stars Bronze = fewer than 400 stars When the boss appears, try not to touch the laser beams because it depletes your stars. It's easier on the second play-through because you know roughly where to go, or at least where not to go...
