Didn't see a thread on this so thought I'd see if anyone else has been checking it out?
For those who don't know, it's the game that was started as a Sonic fan game but then transitioned into its own IP. It's on Steam and GOG and coming to Wii U soon apparently.
It's currently sitting at 10/10 on steam user reviews and is quite seriously the best Sonic game in 20 years. Seriously!
It's very similar to Shovel Knight in the sense that it doesn't feel like an ode to retro games, it actually just feels like it'd been plucked out of the past. In the same way Shovel Knight looked like the best NES game they could've possibly made, this looks like the best Genesis game they could've made.
