Here is my opinion:

Main Worlds:

1. 1-A: More Than Three Choices
   
2. 2-D: Modular Shell
   
3. 3-7: Odd Even Numbers
   
4. 4-B: Mess Hall
   
5. 5-B: Clutterspace!
   
6. 6-10: Rainbow's Blessing
   
7. 7-7: Supernova
   
8. 8-A: Stable Loop
   
9. 9-E: Signflip Master
   
10. 10-10: The Toybox
    
11. 11-A: Return of Operators
12. 12-10: Bypass
    

Omega: Ω-19: The Problem

Part 2 Worlds (For solving):

1. T1-5: Not What I Asked For
   
2. T2-2: Corner Case
   
3. T3-5: Straightforward Puzzle
   
4. T4-3: Mastery Mystery
   

The three mega levels:

#1(Hardest): Kina's Masterpiece

#2: The Labyrinth

#3(Easiest): Chromatic Monolith

Mine for part 2(the main chapters)
T1:T1-4

T2:T2-6

T3:T3-6(new version)

T4:T4-5(old version, unlock focal point)

My thoughts are 1-10/1-C (can't decide beween the two), 2-C, 3-C, 4-B, 5-B, 6-10, 7-B, 8-6, 9-E (solved it before but had to reset my save due to reasons, and I am dreading having to re-figure it out), 10-C (10-10 was easier than I thought, but it's definitely the more intimidating between the two), 11-4, T1-7, T2-4, T3-5 (I solved T3-6 the intended way even before the change), T4-4.

For what comes after T4, here are my thoughts in base64: MC01LCAxMi0xMCwgRVgtNCwgT21lZ2EtT21lZ2EgKGFwYXJ0IGZyb20gdGhhdCBvbmUsIHByb2JhYmx5IE9tZWdhLTU/KQ==
