i don't know where the game uses 'rotation' theme, i liked checkpoint mechanic. visuals are quite simples, maybe you can use some particles and lights, that usually make look better a game 

nice game man! good use of the assets available. don't see any rotation tho

✔️ Good use of assets; the game looks nice!

✔️ Nice to include optional gems, allowing you to explore to find them all.

➖ The implementation of the rotation theme didn't really add much to the game.

the art style is really amazing as well as the level design is fab

Like the speed of the character! Cute name and character too. 

Neat platformer, but I'll echo what I see other commenters mentioning that I don't really feel 'rotation' in this

Unfortunately I saw no rotation, however the game itself is nice and cute. Good job on the retro style!

Like the monochrome, but can't really see the theme?
