Interesting, and I've saved the crewmate.
Add a music first, you can do that in the main menu of level editor

'Esc'
Just something to be aware of, the walls are inconsistent in many rooms on both sides of warping direction.
This includes:
'You're wasting by reading this' -->1 wall tile more at the right side.
'Help I'm looping and can't get out' --> 1 wall tile more at the right side and left side each
'Down Spike Dead' is very inconsistent in walls. Although I understand you want to make both ways possible...
1. Your warp token destination can lead to player getting stuck in walls. Leave a pixel place above and under the destination to avoid this.
2. After you've taken the warp token, go right and flip, you can get stuck in the 2 pixel width walls below.
'Bittersweet Harmony' --> 1 wall tile more at the right side
The design is good, and I find the coding interesting. Just be aware of the wall tiles placement when warping is involved. Never underestimate player's ability to go the wrong way
