Warning- This gets HARD. I'm talking "press spacebar 4 times while falling in less than a second" hard. All levels are possible, though, so keep trying. Platformer. Press spacebar to switch. Yeah, IK this isn't really a rainbow, but it follows the color scheme found in @My_Peeps07073 's (my) https://scratch.mit.edu/projects/911624949/ and originally in my https://scratch.mit.edu/projects/905446592/
I would advise you to get used to the color pattern, as going from red to blue takes one change, whereas going from red to purple takes 4.
