Hey dude, amazing update!
The game is looking really good, and not like a "jam game" at all. The doors and moving platforms make exploring the level much more interesting(and actually required now, since you could just rush to the teleporter in previous versions).
I feel, however, that it's now quite easy to get lost and wander without direction. I believe this could be easily fixed by adding some "landmarks" around the level. Could be some special tile or background element that shows more rarely, a save point, or something else. Just something that helps the player mentally map the level. You could also add shortcuts around the door switches, so you can quickly get back to the "central" areas after toggling them.
