Easily one of the best Sonic games ever made, serving as both a throwback to the Sega Genesis classics while including some new content of its own. The remixed older zones is a wonderful idea and the new zones are awesome. The whole damn soundtrack is MWAH! CHEF'S KISS!

But here are the evil parts.

32 separate Blue Spheres special stages for some unlockables and two hard achievements. If you thought the ones in S&K are hard, these are gonna piss you off.

The giant special stage rings are hidden in odd places. It's not like with S3&K where you can accidentally run into them very often.

The new special stage for the Chaos Emeralds is sporadic in difficulty. The 5th stage should've been moved to the 7th. Pretty damn aggravating.
