Thanks very much for playing the game even after the rating has ended, this means a lot! :)
Glad you liked the ambiance of the game. And yes, I was aware of the 3rd door puzzle, that's why I added the literal explanation on how to pass it. Unfortunately, that was the "quick fix" for the problem, I didn't have much time left to actually make something different about it - but yeah, I'll definitely try to test it more and focus on the level design. Thank you for pointing that out.
