An inspiration to many side scroller, "horror" H-Games.
The beginning was nice, but later on, went from easy, to normal, to annoying, not hard.
Gameplay, 4/5: Pretty Good
The basic controls are fine, and when it works, it's great. There's not a whole lot of enemy variety, but they're done decently well for the most part. There's only one weapon that you start with, and no armor system or whatever. You have a decent amount of health on Normal, and have decent amounts of ammo. It's a slower, more methodical game. Overall, the base gameplay is great, albeit a bit lackluster.
But there are a whole lot of annoying parts to it, for example:
Insects. In the sewers, they crawl on the wall. They can't interact with you, nor you to it. Sometimes, they crawl on the wall until you get close so it INSTANTLY hits you, and you can't do anything other than either, wait at a distance, or just take a hit, because it's intangible. Repeat this several times until you beat stage 1.
Jumping mechanics. Sometimes it's hard to tell where the ledge is, and jumping to the side doesn't count, you need to jump straight up. You also need a running start to do the long jump. Ledges either feel a bit too long, or a bit too short, and it's annoying. Also, I got stuck in the 1st level, because I found the exit, pushed the box, and jumped over the planks, and then couldn't get out because I didn't think I was supposed to jump into the light, and so I was softlocked. So I had to restart the whole level.
Enemy amounts. In the beginning, and middle, it's manageable. In the end, the amount of discount facehuggers are annoying. From the hallways, to the facehugger spawners, they just keep coming and constantly fiddle you. They're not even hard, it's just a gank fest.
TBH I want to rate it lower because of how annoying it became in the end; think of Dark Souls, and all it's own ganks, it's almost like that.
Again, the core gameplay isn't bad. It's the enemy placement and map design later on that sucks. Too bad!
Audio, 4/5: Nice
Not much to say, the character has a few lines, moans, sex effects, etc. There's no music, and you'll be hearing the same few sound effects throughout the game but... It's fine.
Visuals, 4/5: Good
The main game is pixel art, and it's done pretty well. The backgrounds are also nice, and work fine with the enemy art style. The CGs are drawn, and look fine. I don't think the CGs are the greatest looking, but definitely not bad. Environments are nice and distinct. Overall, it's pretty nice, but nothing made me amazed, no dynamic lighting effects and stuff, for example.
Story, Eh/5: Eh
Eh... I can't really be damned to score it since it's so little. The premise is that you wake up, see people running and screaming and zombies and stuff, escape, shoot a zombie cop with it's own gun, and try to make your escape. The starting area makes no sense with the intro, and the insta-death pitfall is literally the only one in the game, but...
The ending is ok as well. It's a bit of a cliffhanger, and just basically says you escape but your body has already began changing.
TL;DR, 4/5: Decent Game.
It's definitely not the most well polished nor well designed game, however, what it tries to do is pretty good. The controls are great, and balancing in stage 1 and 2 are good. If given more time, refining, and depth, it'd be a great game, but as it is, there's a lot of flaws in it with intangible enemies, and far too many tiny enemies. The art and audio is good, but the story is... just... there. Play it, suffer in stage 3, and then write a good review.
