Well written with good characterization and progression. Renders are very good and characters attractive. There's pretty much no fetish material in, aside from the poly romance itself, and perhaps the minor age-play element.
Gameplay wise, the game and story rolls along no matter what you do, so it's extremely light on player interaction. You get to make the occasional choice but with only one exception (that I found), these only affect the immediate scene, and have no effect on the overall plot. This means you can easily quicksave before a scene, play through it, then reload and try the other variants. I found two different endings only, and the path to each was fairly obvious. So basically, this game has a single linear story/path.
Honestly, my only regret with this is that it isn't bigger. Would have loved more paths and options for fetishes and such. I'm not saying the game is light on content at all, simply that the single path on offer was good enough that I wanted even more by the end.
Recommended.
