• Sonic 1's Bonus Stage... hell.

• Sonic 2's Half Pipe... hell depending on Tails' reaction time.

• Sonic CD's UFO Chase... actually very fun. It played well and was not all that complicated to learn.

• Sonic 3's Blue Spheres... everyone's favorite. And I definitely see why.

These have nothing to do with the actual level, I just wanted to elaborate my thoughts on the Bonus Stages in the classic Sonic games, as this level is based on them. Represents them really well, but I can't give it any higher because of the artstyle and it just being a recreation of it. A 6 is gonna have to do. Not really a 5, because it plays rather well imo.
