It's been a while since I played this set. Here's what I think of the new update, based on what levels I've played so far.
#17 Massive Mindset Shift (outside blocks from #107 Lazy Hourglass) I like that you updated the hint in this level, but...
#18 A Moon Shaped Pool (blue walls from #37 Blue Moon)
HINT NOT UPDATED just kidding if you couldn't tell
#36 Gruesome Citadel (walls from #88 Which One Next?) Thanks for fixing that nasty cook at the end. You mentioned that you shortened the length of the hint in this level for MSCC, but I read the hint again and didn't even notice anything different.
Moving on, here's some actual feedback on a few more levels:
#37 Repulsive Shadow Keep (walls from #16 Two Sets of Rules) I figured out the start of the level, and I feel so stupid not being able to see the solution. Seems like that's the hardest part of the level though, as the rest felt like a breather, which I appreciate.
#40 The Internal 3D Dungeon (walls from #58 Bowling) Still not solved. The beginning is so hard!
#41 Eerie Crypts (walls from #47 Flame Thrower) Certainly not what I expected to see from Flame Thrower, but not an unwelcome surprise. Unlike most people I don't mind blue wall mazes (which I know will make you happy), so this wasn't so bad for me. Also, the fake-out in the top room is perfect, just because there's no point in going to that room whatsoever.
#42 Android Temple (walls from #90 Lichenstein) Not sure how to get past the sliding teeth. There just isn't enough time to run from underneath the ball back over to the teeth, unless I'm supposed to use the recessed wall for whatever reason.
Didn't get very far today, hopefully I can solve more soon.
