The game is a bit confusing. I wasn't sure what closing the door does, or the difference between leaving it open. I see a percentage at the top left of the screen that gets lesser and lesser as time passes, and even goes negative, but I do not understand what it represents. My health? Power? Chance to open the elevator?
the controls are also a bit confusing - i think those could have been written in-game to make for a smoother immersive experience. I could hear monster sounds but could not see anything, wasn't sure if I was supposed to react to something. Sometimes the elevator seems to move by itself without any user input, which adds to the confusion.
Nonetheless, I liked the atmosphere and it did establish a good tone for the game! So good job on that!
