Story: 4/5
The story is about a demon king (Or should I say prince?) who made a peace treaty with humans and lived together in harmony. He's decided to adapt to human culture by opening a bar and becoming a bartender. You know, I was going to originally give the story a 2/5, but learning a bit about the protagonist's back story, it was interesting and good enough for me to read more of it. However, the other short stories of the other monster girls or people were either okay, or not good.
Characters: 4.5/5
There weren't many interactions with the side characters, but I did find some of them interesting. But, the maids and a few others were great. We learn a little bit of their back story, so it was nice. But, learning more about the protagonist's back story as a demon king/prince was actually really good. I just wish they give the mermaid more interactions as they did with the other maids. Also, some of the tidbits of minor characters were cool to see, like seeing the hero's interaction with the demon king/prince.
Art/Visuals: 5/5
High-quality art and there are animations in the H-scenes. Some are good, and some are hot. Also the designs of the character look good. Especially the UI and overlays. The person or people who made this game really put a lot of effort into it for a RPGM game
Voice & Music: 5/5
The voices match with the character and fit in well. I also wasn't expecting the voice acting to be in Chinese, which was interesting. However, after going through the game and the scenes, the VAs did amazing in their voiceovers whether it is just a normal scene or an H-scene. The music is either decent or good. It is a bar game, so it sets up a bar's atmosphere. To be honest, there also not much to talk about here.
Gameplay: 4/5
For a RPGM game, a lot of effort was put into it. It a simple make a drink game. The only rng elements are the black jack to earn a bit of more gold which is used to buy gifts for your maids or boosts to get a monster girl to appear to unlock their h-scenes. As you go through customers and customers, you'll unlock the next chapter and scenes.
Overall, 22.5/25 = 4/5, The grind isn't long, nor is it short. To be honest, it just right. You can see the effort that was put into the game, and the story's focus is mainly towards the barkeeper/ demon king. The h-scenes were good!
