Easy on the eyes and with some pretty decent controls. Unfortunately the level design is inconsistent and often feels like it was not play-tested properly. One part of the game I believe requires you to make use of the fact that knockback will always send Sonic in the opposite direction of where he is facing, rather than from where the attack is coming from, to progress. The only other time I've seen this was in Castlevania: The Adventure, so yeah, that's not good.
