It's short and sweet, with plenty of little extras to find that can extend the playtime if you're willing. The minigames in the hub areas are fun, and exploring those to find the next level is a good treat. I'm not particularly fond of how 2D Sonic controls in conjunction with the stop and go level design that tends to creep up at least half the time, but this one was pretty enjoyable all things considered. Being able to play different characters opens up even more paths, and having a partner that gives you an addition to your moveset adds a lot of replayability. Very possibly my favorite 2D Sonic, although I'll admit I've played few.
