So I've compiled a bit of info from the current threads. I'm going to list the changes I'd like to make here, as well as adding a few of my own ideas. Let me know if you disagree with any of them.
1. Cut Zephyr Manor's length down by a room or two and tone down what is there.
2. Cut Rupture in Reality entirely.
3. Cut Cave of Lost Pride entirely.
4. Cut Sand Castles of Doom entirely.
5. Replace all of the sprite graphics with the default ones for now.
6. Remove the eight void rooms and make beating Bowser simply lead to FirePhoenix's "surreal" sections.
7. Take the now-removed mountain void room and make it a regular world 7 level. Move Morel Mountain to world 2 to Football Canyon's place.
8. Cut Buried Graveyard entirely and move Weeaboo Manor from world 2 to world 6 (replacing it).
9. Cut Snowflake Cavern entirely.
10. Cut Confusion Chambers entirely.
11. Cut Chateau of Storms entirely.
12. Move Switch of Many Hues to world 7, and move the green switch to world 3.
13. Cut Into the Water entirely.
14. Cut Cave of Elements entirely.
15. Swap Sinister Dungeon and Treacherous Tower, and remove the reversed controls gimmick in Sinister Dungeon.
16. Cut Unearthly Hollow entirely.
17. Cut Wieza Niebo entirely.
18. Remove the underwater portion of Toxic Utilities.
