WASD to move blue, arrow keys to move brown. Press down to stop moving and float in midair. Press space to restart the level if you get stuck. Brown can't go through blue, and blue can't go through brown. Neither can go through purple. Get to the edge of the screen to complete the level.
Currently there are only seven levels, but I plan to add more in the future. Feel free to remix and make your own. It took a few days to get down the movement physics and I stole a bit of the script from my friend, nightfalcon123 to help me with it.
