After getting halfway through game, I realized it wasn't for me, far too much emphasis on anal and bdsm, however I will try and ignore that and focus on the objective technical aspects.
Artwork is fantastic - I love how the game has a consistent color palette of dark green and brown, earthy tones to match the setting.
Animations are very solid, had no complaints and never felt like skipping anything - despite my aforemented disinterest in the specific fetishes.
Dialogue is competent, was obviously written by an english speaker or translated well.
Only mechanical downsides would be a somewhat lacking feeling of choice, yes you can prioritize one of the daughters or the friend's girlfriend, but overall, the main events seem locked on a set of rails. Second would be extremely punitive key junctions, like getting lost in the woods or failing the trial tasks. While I understand these are part of the story, it seems more like a plot armor to relieve workload from the dev at making alternate stories (an idea would be if you fail to complete the trial tasks, it shifts from a harem-bdsm game to mc getting dominated by the mother, etc).
Anyway, overall a solid entry, just not my cup of tea, however, anal and bdsm lovers will delight.
edit- one thing that deserves additional praise - the UI is FANTASTIC. Like one of the best I've ever seen, everything is perfectly balanced - good color scheme with easy-to-understand stat icons, a good balance between form/function - doesnt have the dumb monochrome flat design found everywhere, but still looks sleek and conveys information. Buttons are perfectly sized, and navigation is easy. If you're a dev reading this - take note, this is what an optimal UI/UX is like.
