But anyway, yeah, this is my submission. Now that my results are revealed, I'm posting this for you all to play. This scored an overall 8.93/10, and you can read the reviews here. I adjusted the unfair pipe area Valtteri mentioned, and that ambiguous route split for the red coin that Quill brought up.
I don't know if it's very apparent just from looking at it, but the level theme is intended to be a clash between a moonlike scenario and sunlike lava, coming together to create a chaotic space experience. Or something. There are two stars, one at the end and one for finding the 8 red coins spread across the whole level.
