I may have something for rusty Jacks and rusty fingers.
;)

Enclosed you will find the very first rooms of the MM2 version of my Midnight Mazes and Monsters. I am pretty sure that there are no cheap deaths in it.
;D

However, any remarks are welcome. A pic shows your possible best result.

It may be of interest to have a look at this webpage:

The movie shows a part of MMM in HD version with critical comments. The first 5:45 minutes are enough to compare with the MM2-version.

Looks nice.  No hint that Jack should go to the left first in the starting room?

BTW when will you finish BNW?

Well, since going right soon stops at the purple door, going left to find a purple key becomes pretty fast obvious IMO. Should I remove the right arrow and the question mark?

(The ideas for the final section are there, but the execution of it is very tough and will take a while.)

Do not change anything right now, let me look at it again.

Edit:  I'm not sure.  I still think a hint is needed in the starting room but that is just my opinion.  I don't think you should remove the arrows or the ?

I have an idea to get this (more) right, but like you said it is more logical to finish Brave New World first.

In MMM original you managed to let Jack's nose turn left in the beginning as a hint of where to go.
