Thanks to leaking on the internet this lost Sonic game can be played. It was a Sonic puzzle game that's rather short. Notably shorter than Dr. Robotnik's Mean Bean Machine. Somehow even less Sonic than that. It's a little confusing what you do. But quickly you will figure it out. I do see some Sonic fans finding some enjoyment in this. Originally a canceled Genesis add-on game. Although you can play this through Genesis emulators. Just confirming that I don't want any trouble. Sonic Eraser is due for a return in the near future.
