Space, Up Arrow, or W to jump Left Arrow or A to move left Right Arrow or D to move right Jumping causes the stage to toggle between red and blue. There are two types of platforms: Grey and Color. The Color platforms toggle between passable and walkable depending on the stage color. Grey platforms do not change depending on the stage color.
Idea from Flipswap Factory of Geometry Dash, and Flipswap Galaxy from Super Mario Galaxy 2. This is just the first stage. I'll work on this later.
