yes the third level was meant to teach the player they can stick to the ceiling, however in making it I forgot to make a level that teaches that in a more approachable way
it was originally a glitch but I thought it was fun so I kept it in, you can use it to get effectively another jump, I should have swapped the third obstacle in that level with that one it was just a long stretch that forced you to stick to the ceiling for an extended period of time. but yeah that was intended to help you get an extra height
