Don't blame me for making 4 versions, it's my best level.
Changelog:
-Ice section is almost entirely different.
-Added more enemies.
-Crystal joe is not endangered anymore.
-Changed even more backgrounds and soundtracks.
-Added decorative crash rails.
-First Yoku block puzzle near the end is no longer skippable.
-Added the funny hitkill lasers from mm2 (they don't hitkill you actually)
-Moved the secret prize room upwards in the screen it was.
-Added some spikes in a pit
I don't even know if there's anything else.
And it also is labeled as hard here now
