VISUALLY the game is gorgeous and the art is spectacular.
CREATIVELY the idea is fantastic. The girl on the cover art is a shinigami who offered to make you a shinigami as well if you serve her in the land of Zekarius the Floating City.
STORY AND GAMEPLAY are crap. Story is nonexistent. You get to know each girl and then you fuck her. Standard hentai game writing with nothing unique to be found. Characters fall into tropes like tsundere and whatnot. Factions in the game are pretty shallow and unimpressive. Nothing to really set this game apart. Meanwhile the gameplay claims to be a management simulation experience, but its SUPER LINEAR. Some upgrades are objectively superior to others, so of course you'd get those first. Some staff layouts work and some don't, there's no room for creativity. The "Management Simulation" is an illusion, your playthrough will be identical to mine unless you want a game over. Playing around with things discouraged. For the first 2 hours of the game you're actively told via dialogue, exactly what to do. Even after they stop directly telling you, the game design makes it clear what to do. You have more freedom in a game of PacMan than you do with this "game".
Story and gameplay are key to a good experience, and this game is very mediocre in both respects. If it was a short game I'd say you should go for it. But considering how many hours this game demands, I encourage you to play anything else. This is not worth your time.
