Blue Spheres 1.1

Blue Spheres is a simple game in which you need to collect all the blue spheres to complete each level. However, you need to avoid the red spheres. You are supposed to move forward on large checkerboard arenas and 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.
