Okay, I downloaded this. Sadly, I don't have much good to say.
FIRSTLY: Main menu and the loading screen was blatantly ripped straight out from
Wolf's Thanatophobia. It didn't look like it was even edited at all.
Secondly, I don't know what you're trying to achieve. The game sounded serious from the summary and the menus are dark and gritty looking, but then again, they're from a game that is dark and gritty. I was expecting a scary game and a creative game, as with a premise like that, you can do pretty much whatever you want. It's a shame the design and segments were all around very bland. Mixed with crazy colored lights.
And you obviously tried to pull off some scares there, which would have worked fine if the rest of the game had an atmosphere to support it. It didn't. The background sounds were good. Actually really good. If the game was visually as appealing, it would be superb. So that's a plus, the ambient sounds were nice. The other sounds weren't. Jumping, well, when what used to be the stock jumping sound seems appealing, you know there's something wrong. It was just annoying and made me feel more like you weren't clear on what you were trying to achieve. At least that's the sense I got from it. Also, the custom zombie sounds factor into this too. If this was supposed to be funny, then I'm sorry, it didn't work that way either.
The hurt HUD was terribly pixelated and it had a black background. Even having a transparent background would have made it far better. And there were parts that I died in for no reason. Okay, I know the reason was hurt zones, but there wasn't any indication of were there was gonna be some, so I game overed over not knowing where I am allowed to go and where not.
That's all I got now. Sorry if I seem harsh, but I'm just being honest. It was poorly put together, it wasn't fun and it wasn't scary. I had a "what the hell is going on" feeling many times, but not in the good sense, more in the "what were they thinking" sense. You got potential here, work on it and you can have something really good. Practice is all it takes and I hope to see this title done well at some point, as the plot (although there's not much) allows for so much creativity. The potential is there, but this title just wasn't good.
For my final score, I'd give it a 2/10. Just for the ambient sounds which I found good and that I think the actual fighting with the fat zombies isn't too bad (although the crawlies is). I know you can (and hopefully will) improve, I'm not trying to crush your spirit, but if I just said that this game was great, you'd not know to improve.
