An enjoyable classic platform Sonic game with better visuals, variety of playable characters, the pace is slower than other titles. The abilities given by chaos emeralds kinda cool, I want this mechanic will be featured in next games as well.

It's fine, easily the worst of any classic-styled Sonic game so far, but it's fine.
But for 60 bucks? No chance in hell, save your money and get Mania instead.

This has to be the worse Classic Sonic game by a large margin, it's all recycled ideas with some cool emerald power ups that you can barely use and the bosses are the worst bosses in any game i have ever played. They will be visibly in attack range but if the game decides its not time to damage them yet you will literally pass through them and fall to your death and there is absolutely no indicator as to when they are vulnerable or not you just gotta know!
