A really fun game, I especially like how you've used the idea of an ouroboros as something other that a snake remake, and instead a means to explain the looping story of the game! The art feels quite polished, and I especially like the transition into looping a level. The looping mechanic is also well done, and I like how you're encouraged to not set off certain moveable platforms in order to be able to collect all the crystals, which gives an additional level of challenge. For some feedback, I would have liked a quick restart button, since I failed quite often (skill issue, i suppose), and it was a bit annoying to have to navigate to the menu and click the button every time. Other than that, great game! Congrats on your submission, fellow Ouroboros title!
