This is a very solid idea, but the game itself is far form perfect.
I think the concept is good, but the game is pretty buggy.
I fell through the floor on the recycling station several times.
The enemies stick out through walls and can hit through walls. And follow the player even If the player is a floor above them.
Buying bullets is pretty much an infinite money glitch. You spend 1 point to buy 15 bullets and then are able to sell them 1 point each.
The ladders work kinda funky. While I get the thinking behing making you hold a button to go up, just by snapping players position up. The problem is that when you are already on top of the ladder, you can do that again and end up one floor even higher.
However I quite liked the audio. For an action horror type game it was fittingly unnerving with the buzzing and foosteps. The enemies are very gross, which I think is a job well done on the graphics end.
This is a solid concept, but still needs some work to be a great game.
Best wishes on the way ahead!
