This is a sad 4-star rating.
It is a nsfw management game with actual gameplay, and it boots, didn't crash, so that to me is automatically at least 3 stars, since these are already decently rare. It gets 1 more star for the concept.
However, it commits several sins:
Sin the first: No story, no characters, not even the one you can come up with
To keep this very short: this game doesn't have a story or any real "characters". That's fine, some great games don't have characters - I can think of Free Cities and Corrupted Saviors where the characters are largely automatically generated and are ultimately a story is developed around the actions you take. This game has nothing, which means you really don't care about anything in it. That also reduces your investment of what you are working towards.
Sin the second: Way too much uninteresting micromanagement.
I - and I suspect most people here - like management games. I don't like micromanagement that much. The game lets you automate parts of gameplay closer to the end of the game, but even then it's gated pretty hard (until you enter free play) and doesn't cover everything. The game ultimately lacks larger scale management decisions, so if it did let you get rid of micromanagement there would be very little game left.
The micromanagement isn't even that interesting, unfortunately. It's just a mad dash of dragging images around as fast as you can go. It distracts you from the nsfw side of things, and this only get worse later on. I'm going to be honest, I don't even know what the game looks like after you get 4 monsters, it's just a blur of trying to make sure everything is at the right place at the right time.
Sin the third: Underdeveloped late game
Some people have mentioned that this doesn't feel like a complete game. I don't know about complete, but the later part does certainly feel rushed and somewhat underdeveloped. Perhaps I skipped out on something, but the surface doesn't really gel with the few objectives the game does give you. There is an elaborate system from creating the highest tier creatures, and they have high requirements for breeding, which I actually never reached because I was too busy putting out fires elsewhere. By the time the game was over (it's a short one) and free play was in, I thought I'd be able to sit back and see my creation. Turns out, the over ground facilities can cause STDs which can really fuck with pretty much everything when you're not paying attention. Further, creatures deplete and need fixing or replacing, and when you have 20 odd creatures and 40 odd workers, this requires constant maintenance.
Sin the fourth: What is this, a game for ants?
Others have mentioned it, but you really, really need to zoom in to see any action, and you will spend essentially no time zoomed in if you are playing. And you will be punished for not playing. The art itself is a bit weird, the girls look pretty decent but the monsters are subpar. There are several animations, and they are good, which is cool, I wish I had the time to see them.
There are other minor issues, but these are certainly the blatant ones worth pointing out.
I do have solutions I can suggest:
1) Add characters. Maybe add one immortal slave that has a story, maybe flesh out the merchants. Do *something*. It doesn't even take more than 3-4 characters to have a story that will be good enough. I'd suggest allowing a deeper level of individual worker investment and customization, but that runs contrary to how disposable the story makes them.
2) Drag and drop gameplay is... fine... for the first few moments of the game. Allow full automation much earlier, and focus on investing in infrastructure and upgrades. As it is, the game plays as one of those dinner dash games. Let players breathe and take what they are building in. And allow late game debuffs like stds and purchasing condoms and cleaning to be automated.
3) Make the main repeating quest at least pretend to integrate the above ground structures. It feels like there should be at least 4 more main quest goals.
4) The characters should literally be scaled up so they are easily viewed when zoomed out at what I'd call "gameplay" zoom levels. Art is subjective but I would redraw parts of every monsters aside from the goblin.
