An extremely unfinished mess but a very interesting one, it's unexpectedly super hard and bafflingly designed but Sonic Team is also clearly experimenting both with how to design characters outside of Sonic and how Sonic can move in a 3D space, as the new level design seemingly intentionally allows for you to do fun bullshit with momentum physics.

Also the final boss is the most anime bullshit Sonic Team has ever been and I'm really hopeful they keep it up cause it's incredible.
