Honest review...
Some very interesting 'monster' girls helping MC out on his deceased parents' farm within a slow grind sandbox world. The backstory/plot unfolds gradually as more and more 'love interests' show up...
The "heart" icon is a simple walkthrough guide if you're not sure where to go, what to do, what to buy...
The Koikatsu renders are good, but the manually-constructed environments sometimes have mis-aligned parts (like wood walls not lining up at the seams). Being a dev who creates custom maps in Koikatsu Studio, I know the challenge in that when starting out, so I'm not knocking the dev for it. Just pointing it out so - if in the future any scenes are tweaked or images re-rendered... those tiny non-critical issues may be tweaked.
As far as sandbox interface goes, it's a bit bulky. At times, text names of places overlaps the text for money and time, even randomly changing font sizes with mouseovers... But in its simplicity and scale, the interface is not difficult to navigate.
Gameplay-wise, a few kinks are avoidable, a few characters are fun to interact with, but it takes around 40 in-game days (or more) to progress relationships beyond hugs and kisses.
I had fun with version 0.5, but don't imagine I'll proceed beyond this point myself, due to aspects I discussed privately with the DEV.
arcaos is very approachable and understanding. I sincerely hope the game becomes a success for those who enjoy the kinks/fetishes/activities and relationship dynamics portrayed within.
