1) seems to be fixed
2) after you die, the message comes back and you are forced to go through it time and time again now which can become cumbersome for the player. i did notice that it now says to press a button to progress which is much better than before. still needs a little work but good progress.
3) seems to be handled with first paperwork (player could pass this up on accident but most likely will look at it). you may find it useful to display a text at the bottom of the screen with the player controls just while the player is in the beginning room. you could place 2 trigger tiles next to one another in the first hallway and as they exit it turns the text off and if they enter again it shows it again. this way it will only display in the first area and the user has no chance to walk past the paperwork. like i said they will probably look at the paper but if you can make it 100% that they see the controls without it obstructing gameplay, that would be the better option. well done on the progress, it is much better than the prior revision of the game already.
4) door stays open until you are out of the way. considering fixed. well done
5) you said future iterations. i will wait for a better response when they change

8) NEW ITEM: please look at the door that is near the end. it matches with the grating and is hard to tell that it is a door. consider a slightly different color or pattern scheme for the doors so they don't blend with either floor tiles. a quick fix would be to change that grating tile to the concrete floor tile with the door on top of it for right now so there is a better separation of the two.
I like the addition of the overhead beams that block the view in some places. that is a nice touch. I am excited to see your progress and fixes. keep up the great work and i look forward to your next update. let me know when you do more so i can look it over again!
