I really like the concept and application of the theme here! I do think the game would benefit from a few quality of life things like an indicator for the order of the colors as you swap through them, and a clearer indication of what color the greyed-out slimes/platforms are. I agree with the other commenters that the temporary platforms had some unintuitive behavior, but I think this could be mended by showing a timer and the color their will react to. I also really appreciate the quality and frequency of the tutorial signposts.

Thank you! I like the idea of a timer to show when platforms will change colors - it just didn't occur to me when making the game. I saw something like that done in another game submitted (Colour Platformer by jbalsby https://jbalsby.itch.io/colour-platformer ) and immediately regretted not doing that :)
