This definitely needs some work in the gameplay department. It describes the game mechanics, but then offers effectively no option to play by those rules. Fighting zombies is a waste of resources, but the developer fills the levels with zombies to the point where most are unavoidable. RPMaker demands that you walk around in boxes which brings along the usual jankiness when it comes to running into overworld enemies.
Shooting your gun, which we're told draws more zombies (afaik this only happens during a scripted scene) is worse than using your knife in combat. You're told that you can use the resources we get from the first quest can either be used for crafting or sold for bullets, but we're railroaded into the second quest before we even get a chance to see a crafting station, so we have no idea whether or not selling or crafting is the right call. We're also given no indication about how many resources we should buy, since there's no benchmark for how common infection, poison, or damage will be (Medkits also don't say how much they heal).
I wouldn't harp on a porn game for the 'game' part if it wasn't a detriment to the point where I can't even get to the porn part (the part most people care about anyway). There's also no real indication on where to go or what to do on the second quest. You're told to 'take out the raiders' but there's no indicator on how many are left, or that something will happen when you find and kill all of them, or if you need to go somewhere in a suddenly massive map.
