Well, since everyone is talking about this game. I will talk too. I finished a little ago everything, and now I can proper talk about.
And is AWESOME! Have everything I wanted in a Sonic game, I can't ask for more. I even dropped a tear of joy when played! Let's first focus on the good things:
"Good Things":
The game is nostalgic, of course, but the game don't rely only on nostalgia, no sir, the game can hold for himself pretty well. Each stage only have some landmarks from the past, but most part of then are completely original. You have a lot of paths to follow in the stages, and each path can take a different skill level.
Classic Sonic
