Other slightly-off things I noticed: -It seemed like my timing was off with the boss. Like he should've been coming back on-screen more quickly. I've trampled Robotnik's Revenge a LOT, so I trust my sense of timing here. -I didn't feel like I could quite reach the breakneck speeds normally experienced, though that might just be the widescreen throwing me off. Not that it was laggy, just that Sonic literally wasn't as fast as he should be. And a compliment: -That invincibility music? AWESOME. I absolutely LOVE the ramp-up sound at the beginning.
