Each time you catch the appropriate colored shape, the platform rises slightly, resetting once it reaches a certain point, but getting more difficult at the same time. If you catch a colored shape that doesn’t correspond with the color of your paddle, it’ll crunch down the arena and change colors. If you’re green and you caught blue, you’ll have to catch blue from now on. If you’re blue and you catch red, you’ll have to stick with red. If the arena gets down too far, it’s game over. You’ll have to pass the stages for obtaining points that you can spend on different extras: magnet, automatic passing of the stage, additional life, time dilation, score multiplier.
