Decent premise, definitely not the best execution.
I won't comment on the models because that is a very subjective opinion and I'm sure anyone looking to download the game can look at the images and form an opinion based on their own preferences before downloading.
Let's jump into what the game does right:
- It doesn't spend too long building up, neither does it jump right into the action within the first 10 frames. There is some decent build-up which is nice.
- There are some "implied" sex scenes, but not explicitly shown. This could be considered either a good or a bad thing but for now, I'll classify that as a plus. It can be tasteful if some things are left to imagination, but will quickly get annoying if there is not a single explicit sex scene in sight.
Now, for the bad:
- There are absolutely no choices as of v1.0, Chapter 1. The player has zero control over what happens, even with regards to determining WHO the MC's mother will sleep with. At the very least, there could have been a choice between willingly getting out of the way to allow the mother to get laid or to try and resist but she gets laid anyways.
- Pointless exposition. Of course, there is always an expected amount of dialogue or narration to read in most Ren'Py games, but this one in particular is a visual novel with copious amounts of unnecessary, long exposition with no payoff - so far at least. Having choices or shorter, more concise narration would have helped keep things interesting but for now, I think the game might only appeal to people with too much patience for it.
All in all, it's a decent story but that's about it - it feels like something that is better suited for erotica than as a game.
