Alright, having actually tried this a bit now... yet again, the epitome of bad sandbox. So much clicking around, so little to actually do. Takes over a week to even unlock a 2nd location. I can't imagine how much worse it'd be without URM to cheat all the scores up. I think it gives you 2 tasks, and then you get no hint at what to do next for almost a week, because there's nothing to actually do after that. You literally just click around the house and talk to everyone and sleep a few times. If I didn't increase everyone's points, it might've been more like a few dozen times before even getting the 3rd task. It's absurd.
This is why so many people hate sandbox on here. It's very harsh to criticize so heavily on a 0.01 version, which is what this actually feels like... because OF COURSE there's not a lot in it yet... and of course the sandbox will feel empty and unnecessary like that... but my god it's bad. And have to click "Look around" just to get the little navigation menu to pop up all the time? You're adding extra clicks for no reason. Just have that navigation menu up at all times.
Also, I think at one point I talked to Kaoru, and it was like, "Read a book with her?" in the morning, but I didn't actually have a book yet (afaik), so I went to the school/library with her first, then the next day I didn't have that option in the morning, so I talked to her, then I checked the phone or Tasks list, and couldn't talk to her again without leaving the room and coming back. Checking the phone or Tasks list shouldn't break things like that. At least it was an easy fix, but still.
Honestly, there are almost no sandbox games I like (though there have been a couple), but I HIGHLY recommend turning this into a normal VN. Remove the grind, all the clicking around, the map, everything. It'll allow you to focus more on everything people MIGHT actually care about. Any story, the characters, and arguably most importantly, the sex scenes. (though, honestly, I play these for the story and choices. I can just watch regular porn if that's all I want)
Especially as a first game, with sandboxes so hard to get right and needing SO MUCH content (and WAY less grind) for seemingly most on here to enjoy? Not to mention, a lot of people (as far as I can tell) don't like mini-games and want a skip/win button... so it's kinda a waste of time to put them in. Arguably, anyway.
Of course, this is just my opinion... and to some extent, if you want to make your game a certain way, you probably should. You'll never please everyone. There might even be people on here who feel almost the exact opposite way, and basically hate normal VNs, because "they're so boring without gameplay" or whatever... but like, I'll go play Wildermyth or BG3 or something if I want gameplay, imo... the "gameplay" in VNs usually just detracts from the game. It's almost never good. Plus, even someone like me, who is usually here for the story and characters, is also kinda here for the sex scenes... and shoving gameplay in our faces just slows us down from getting to the parts we might actually enjoy. 
I encourage you to consider this, at least... and then ignore it, if you wish.
I'll add this to f95 Checker and come back in like 5 updates or something and see if I consider it worth keeping an eye on, or dropping at that point. Definitely not worth continuing currently. (At least, not for me. Some may like it... but based on everyone complaining about the grind, probably not worth it for anyone right now, tbh.)
