Might as well get the good out first though: This game is flipping beautiful. The level and character art is outstanding and clean, and was a pleasure to look at. The enemy design was also really unique, you totally incorporated some ideas I've never seen before. From that aspect, this game is so good, it almost feel official, and the level layouts were really well thought out, with some crazy awesome gimmicks!
However, the major setback... Is the air control. While for the most part, the controls feel just like a classic Sonic Game, there are a few times where the controls plagued me nonstop, particularly during the point where you're being chased by the giant ball. Once you jump, if you had any level of speed, you are committed to that direction, and it's impossible to maneuver yourself in the opposite direction. You can slow to a stop, but not actually reverse direction, unlike the original games. That, kind of ruined the otherwise seamless experience for me. It feels kind of clunky, and made it very hard to precisely control where I'd land. I got flung to my death a good few times.
If that were fixed, then Sonic Neo Genesis would probably be the best game this year, IMO.And to be clear, I do still really like it, there's just some frustration that could be fixed.
