I just wanted to put in my two cents because... Wow, this game is... Strange. It feels kinda... Mid, in all aspects. Kinda polarizing. I just had to write a review with how MID this game was. So uh... Yeah.
Gameplay, 2/5: It Was Sorta Fun to Explore but Combat...
Literally hold Z as so many people have said. "Building" your "Azoth" (frankenstein's monster, basically, but anime tits) could've been more interesting but no it's just Girl Head + Biggest Tits Body you can get.
The whole side quest part is also kind of... Okay. Still just hold Z to play through shitty combat but getting "masturbatory zombies" for some people or finding someone's kidnapped child was sorta ok.
Like, it was all brainless gameplay, but it never broke so... Yeah. IDK how to put it honestly.
Story, 4/5: Had Interesting Twists, but Got Repetitive.
To summarize, the events flow well enough, but are pretty predictable. The twists are interesting enough. A bit sad, but never depressing, because these people are taking EXTREME actions sometimes for... Dumb excuses imo. Trying to not give examples for spoiler reasons but... If you could skip the combat, it'd be worth playing for the story. Not that it's great, just good.
Art, 3/5: Some are Weird. Some are Good.
There's some... Chibi? Art that looks strange. A lot of the bigger animations look good. Some are a little vague. The tileset and character sprites in the overworld are kinda bad. The female zombies also look disgusting when fighting so IDK how you get those body parts and IDK who would fuck these rotting corpses. But the characters look OK except the blue haired lady who's tits were far bigger than her head, leaving an odd proportion.
Honestly, the gameplay is NOT worth the H-scenes, so just get a full save. Then it'd be fine.
Audio, 3/5: Fine. Average.
Music is generic. Generic RPGM victory fanfare. Some music a bit out of place, like this metal/rock music playing for a basic fight. There's no super loud or bad sounds or music, just all... Boring, but fitting.
Overall, 3/5: Almost Worth the Gameplay.
The H-Scenes + Story MIGHT be worth the gameplay... If it wasn't such a slog. I don't know HOW I got through it I just stopped thinking. It is NOT worth your like, 5 hours of holding Z to skip selecting choices and fighting. And I did all the side quests which were interesting. As many others said, just get a full save and enjoy. If you play it... Cheat to increase your attack or something... You literally don't need to heal for 80% of the fights, maybe once in the beginning, and a couple times near the end after fight.
F to the Zombie Sweepers, they the real ones.
