Generally better than modern 3D Sonic games (of which I have not played that many, but the consensus is that's not a high bar to jump), but I get consistently annoyed with the distance & rubber-banding the game employs. Sometimes I can let the game push me through a speed section across railings or jump pads but sometimes I need to correct or I end up constantly over-correcting.
The character designs are cool, as is the music, but the lack of difficulty and some of the jankiness in the way the game controls just annoys me as I play longer. Not screen-smashingly annoying, more just tiring.
