The GG Sonic devs got to make a not-Sonic platformer with Sonic's brand of shmoovement, and it's honestly better than the GG Sonic games in some ways. You got this heavier slower platforming mixed in with wall jumps, slides and a power dash. I think your default speed being slower makes this a lot more condusive to the GG screensize. Low points are the music isn't as good as Sonic, the bosses are all laughably easy, and it ends a good zone sooner than I assumed.
