The goal of Blue Spheres is to get the blue spheres and avoid the red ones! Play several levels, all with beautiful scenery and music. Move forward on large checkerboard arenas with full of different objects, where you have to get the blue spheres. If you touch a red one, you lose! And after touching a blue one, it turns red. The speed of the player increases over time, making it more difficult. Use the yellow bumpers to jump a long distance. The starred bumpers knock you backwards. Whenever there are a set of blue spheres making a perfect square, you can turn them into coins by getting only the spheres of the border of the square. Collecting 100 coins gives you an extra life. You can change your direction using left-arrow and right-arrow keys on the keyboard. Use up arrow or spacebar to jump.
