The game is pretty much as listed on the tin: a lightweight management sim with H elements. As is par for my course, all H games are granted an extra star because the competition is so pathetic. As others have warned, it is very likely a ported mobile game. However, I am panning it because it was rather buggy, low effort, poorly balanced, and generally uninteresting. Most of the bugs weren't showstoppers (other than the one that made the UI disappear and required fully exiting the game without saving, because they didn't properly test the port nor implement keyboard commands), but were of the missing reference/image/text or typo variety. On top of the bugs, a non-trivial amount of features were either lacking explanation or the explanation was incorrect. To add insult to injury, the game would auto-resume from a paused state when accessing certain screens.
Most of the girls have their own mini-questline (which includes regular match-3 minigames). However, I found almost all of the stories rather dull and the rewards for doing them basically worthless, outside of H-unlocks.
As far as the H goes, there is a decent amount of it. Though be aware that it is almost all monster girls and relies heavily on image stretching/warping for 'animation'.
The progress goals are frequently counter-productive. Almost all of the build/upgrade goals require you to do things that hurt your margins. Fortunately, these can be gotten around by just building->upgrading->destroying a room over and over. Each build/upgrade counts towards the goal. The rooms don't even have to exist at the same time.
To conclude: Meh. If the average H-game wasn't such a sorry excuse, this wouldn't even warrant a glance.
