As a Sonic fan, you had me hooked!
I will say though that the jump feels a bit too floaty for me - can barely change direction midair, so it feels really punishing. Plus, every time you get a game over you have to sit through the intro again... 😅
Besides that, I also couldn't get the slide jump to work? I'm not sure why - maybe I'm missing something - but I tried many many times in the tutorial before I gave up and switched to the actual stage, haha
But other than that, very fun and solid game! Loved it! The dash mechanic is pretty refreshing and the overall style of the game is really nice.
