Although the game has a number of things which could be better, it left some nice impression in general.
The things which were good:
1. The plot. Of course, it is quite banal and uses the basic formula for such kind of stories, but what is important for me here is whether I believe in development of the relationship between the main hero and his lover and whether I care about their story. This is pretty the case, the relationship development didn't feel awkward or cringey. Although what I didn't like much is that the player wasn't given a chance to see the relationship development from the very beginning (the spicy moments), as it mentioned that this is not first time experience between the hero and the lover.
2. The audio part. The voices of the characters were great (and sexy). Also the music is good, some tracks were really catchy.
3. The arts. In general they look high quality (although sometimes some body parts don't look realistic - not saying about the sizes). The animated arts is also a cool idea, surprisingly it looked better than I'd expected.
4. The mini games. I don't really like when the games of this kind have too challenging mini games. Here there are only 2 kinds of mini games and they are not annoying. Maybe for someone it wouldn't be interesting enough but for me it was ok.

The things which could be better:
1. A different game version for Steam is really upsetting. I wish they made a way to get the cut content for Steam players so we don't feel scammed.
2. I guess there's not that much content. Yes, the full story gameplay is around 8 hours, but 2 paths which game consists of have pretty much the same plot excluding some parts. It would be better if 2 paths had 2 different stories.
3. Sometimes I had a feeling of lack of interactions. Would be nice to have more things to choose which affect the gameplay (like which location to visit in the hotel).
4. The arts don't have big variety. The characters' actions are quite the same on all the arts (excluding a few arts with foreplay), mostly they depict a classic sex. It would be good to have some bigger variety of actions and kinks represented (now it's only BDSM there). Also it would be nice to have a top path for Goro.
5. This is a weird strategy that a player has to buy the arts which they have unlocked in game :)
6. The amount and repetitiveness of the content brings a feeling that the price for this game is quite high (comparing with similar games).
7. Also, I guess I noticed a few mistakes in text/audio dubbing. Not critical, but still :)
