The levels felt quite challenging and it was worth the reward when I finally made it to the cookie! The ability to spin the world around you is an interesting concept, even though it can be disorienting. I found myself back to the beginning a couple of times X-D. Maybe if the colour gradient was darker/brighter closer to the end of level it would be easier to navigate.
I would personally remap the controls to SPACE for dash instead of SHIFT because dashing with my little finger was not convenient for me, and it's such an essential part of the game.
Being introduced to new mechanics half-way through the game (the orbs) was also a nice touch and gave a sense of progression to the game, instead of just going through different levels. My only regret is that I didn't make it past "The Dropper".
An easy-to-implement quality improvement would be to add a different audio loop and colour theme for each level.
Overall a nice platformer with familiar elements, a new twist and a decent amount of effort on level design!
