A fanfilm, Basically Sonic: Into the the Sonic-verse. Gives off similar vibes too. Still in the works but comes out "when it's finished"
The ova voices are like, perfect. can't wait to see this animated, they're planning on copying the art style too
They even have original music, which is crazy, and it actually sounds nice
And here's one of their animatics. I suggest checking out their YT channel, their stuff is sick
