The problem a lot of sandboxes have is lack of direction. When you spend more time advancing days, clicking random rooms, and trying all dialog options for the 4th time to try and notice a difference is when sandboxes move from ok to tedious grind fests.
The girls in this game are gorgeous, but this has started to venture into the grindfest territory. No direction on how to get the harem scenes, no way to trigger "hot days" to get to the boat other than sleeping 10x in a row, no way to see how to unlock the scenes you have missed, and noway even see that you missed some unless you talk to a specific npc.
When you have a scene like the watching tv one do nothing but raise stats by 2 for 95% of the game, then suddenly make that same scene a trigger for events later without direction its just not good planning. Now I need to go back and look at every other repeatable scene even if Im maxed stats with the girls to see if it randomly triggers something else?
And I still have 2 random black boxes, one with the mom and one with a sister that wont trigger even tho I'm pretty sure Ive exhausted all options in the leading scenes.
