Playing this this evening. First zone is a beautiful mix of old and new, very well done. Taxman sure knows how to make a Sonic game, that's for sure! I will be getting lost in this wonderful game.
I can just imagine the members of Sonic Team sitting down with this game and playing it for the first time. I'll bet they're awestruck.
Edit: Zone 2.
Beautiful level design, amazing second act, and dat boss. I am saying "wow!"
Edit: More zones. Beautiful stuff. Managed to snag my first Emerald in
Weird Ass Japanese Print Shop Zone.
