TL;DR: Great concept, horrendous execution.
It plays essentially like a flash game, you call one of 3 women, do exact same things, forward to the scene, done with her. After you are done you can call her to the hotel to unlock an extra pose.
When you go through the first girl it feels tolerable enough, but when you get to the second you realise that the text is EXACTLY the same, word for word, regardless if it's a student, milf or saggy grandma. They got same sequence of things you need to do and can do, exact same words they say, there are zero differences besides visuals. So while it may seem like it has variety, it's actually a lie.
UI is quite confusing at the start, top bar may seem like a timer or alert but it's actually just a pee gauge, picking other options is a bit annoying too, for example if you have a card out and you want to make a photo you first need to switch to other action so card wouldn't be in the way. Overall game suffers from lack of care and QOL.
Personally after i realised going through 3 girls isn't the end and you can call them to hotel, i expected sort of an Illusion-like progression, like if you do it enough maybe their attitude change or you unlock even more poses or something. I did the exact same song and dance with one girl several more times but nothing changed, so if there is some progression or ending or anything like this i did not see it and i doubt it exist.
The only good thing i can say is 3 surprisingly good voice actors, i assume entire budget went into voices.
Sadly it's pretty much a lazy flash game that doesn't even try. I wish things were different with this one since the concept is nice, but here we are.
