By far the best Sonic game since Sonic & Knuckles, none of that lame automated stuck in place rolling/spring movment from past sidescrolling3d sonics.

Fluid movement and great controls
Good music (slight old feel to it but with newer bits too)
Remade act 1 zones and more original act 2 zones of previous zones from older sonic games.
and New Zones that feel and play as good as the remakes
both easy and challenging bosses which is a good thing.
Sonic new spin dash ability is a fun new movement.
Bonus and Special zones both annoyingly clunky and frustraiting as they should be in a 2d sonic title.

If this same team make a Sonic Mania 2 with this art style and music but new zones/enemies
then I will make sure i buy it.
