Not recommended Jun 24, 2026
Visually, this was stunning. Narratively, it was a mess. I couldn't make any sense out of the story. The game lingered on the MC getting up in the morning, getting undressed, going to the bathroom, getting a shower, getting dressed... which is all fine and somewhat pretty, but it did it multiple times, taking up a lot of needless time with pointlessly. That would just be mildly annoying if the game hadn't then appeared to quickly skip entire scenes of dialogue that might have something to do with the actual plot. There is long descriptive narrative, entirely unneeded in a visual story and poorly formatted and confusing dialogue. Finally, in a huge personal pet peeve, later scenes refer to events from choices I did not make rather than from the choices I did. In the end, I had to abandon this game. Cannot recommend.

An engaging adult game where you have choices on your characters behavior, gender preferences, and adult partners.

A very entertaining story with loads of erotic content. The narrative and dialogues are witty and credible. It's a low cost game worth checking out.

Short, but interesting so far. Long way to go before its really ready, but already worth getting.

Finally got this game. Needs more content. Promising future. I like that the story can change just by saying yes or no to certain events. Hopefully some of them can be expanded. Maybe also make there be more options not just two. For example games like Guild Wars 2 sometimes you 3-4 options. Same with SWTOR for dialogue choices usually is 3.
