Contender for Best Cyberspace Level #2 (4-3 Rumble Rave)
This level is nice, not extremely linear, has alt paths (even if only for a second)... but the nice thing is that there's not a lot of mandatory automation. I especially like that you can jump in that tower at the end instead of taking the pulley to go down.
