A legitimately under-looked and underappreciated character.
His abilities and sprites fit into the game's style just about on par with vanilla Sonic's quality, and are probably suited perfectly for any gameplay modifications by how simple he is. Most people call him a meme ball, but all the memes are in the poses, which don't detract from the gameplay or character at all and can be disabled at any time. I'm glad you checked through and made sure his offsets were properly done unlike some of the other MB characters, this is a pretty basic thing that I notice others tend to slip up on sometimes. His animations flow very nicely and don't seem stiff at any point. He's got a really nice and cute design that maybe be considered not Sonic-like in nature, but I personally think it has a lot of charm on it's own.
However, that's not to say he's without flaws. I feel like the ear boomerang could be improved by letting you use it in air, due to how you can end up landing in pits due to the vulnerability frames and hitting an enemy at an inconvenient time. Something similar to how Super Mario Odyssey's Cappy mechanic works where you can stall yourself in air, but without the bounce and it instead still homes in on the closest enemy. But other than only that, I'd honestly say he's a perfectly executed character with just enough content.
Overall, 9/10.
I've gotta say, he's pretty fun to mess around with.
