Not bad. Not great, but not bad. Just as a heads up, for the sake of potentially saving those interested 1 hr 30 mins, this review will contain uncensored spoilers for the game.
Story wise, it's goofy, simple but effective. Girl wants a penis using the chopped off ones from corpses and reanimating them with science, a spill accidentally reanimates a corpse, zombie outbreak ensues, girl takes a few special ones home to fuck, before ultimately being shot to death shortly after coming to the realization that this was her fault.
Gameplay wise, it's a generic RPG style, not much to write home about. But I will praise it for being more on the simplistic side, as the more ambiitious ones can be tedious after grinding and micromanaging for too long. One you acquire gun and Level 20, you pretty much sweep everything.
Translation wise, good. Nothing too out of the oridinary and the dialogue (or rather monologue for the most part) is coherent.
CG wise, the art style is alright and the amount is very sufficient for a quick title like this. 7 zombies to choose from (including yourself), with 4 having 2 scenes each and 3 having only 1 scene, all of which possess 2 flashbacks and 2 plain CGs (one for clothed, one for nude). And once you beat the game, which is the only way to unlock the gallery mode/rewatch scenes, you can also customize the characters to have 4 types of eye positions, for a grand total of roughly 88 unique CG customizations.
tl;dr just like the review before me, it's a fun little rompf if you got an hour and a half to burn. That and into the necro stuff, which is 90% of the content, but I suppose you wouldn't be here if you weren't into zombies.
