Wow I love this. I haven't played RE much, but it has some inspiration from there, doesn't it? The bullet management, enemies crawling and spawning everywhere, the occasional jump scare, keycodes and medkits. I think this game sets the mood really really well.
I need to confess one thing, I cheated to get to the ending haha. I'm somewhat bad with bullet management (trigger happy), and I accidentally found out a bug and used it to be able to kill everything in my way. You see, when you pickup an item, before you confirm, you can click it again, and "stack" the dialogs. Then you can click to get the item and you'll be able to get it multiple times. So everytime I found ammo for the handgun or the shotgun I would refill the weapon completely instead of getting the 10 bullets.
The huge enemy startled me A LOT, as it appears out of nowhere in a place you already have been (which is cool). The text messages from the crew and the locked doors added a lot to the experience as well. The controls felt weird at times, but nothing bad. One thing that was kinda odd, and probably a bug, is that I was constantly hearing a buzzing sound on the game. I don't know if that's intended but that's the only thing that bothered me a bit.
Oh, and the ending is so cool. Awesome entry there!
