Ok, I'm still early in the game, but the "sandbox" (ugh) is opened, but the "hints" trying to get new events with certain characters say to enter the room in the evening (they're not selectable and they're washing dishes/couch/out in garden), or go in the garden to see the mom there (she's never there).
I honestly don't understand why there's even a sandbox in this game, you already have menu selection in certain areas, why not just do it that way? Also, this game needs a better hint system or something. Plus what are the stats for? We obviously get "strenght" from the gym, and there's Intelligence, stealth and something called Karma, but what does it do?
Edit: Just want to note, that so far I *do* like the content so far, there's just some things (listed above) that has me frustrated on this VN so far.
Edit 2: Ok, I figured out the whole "day cycle" as there's no real indicator of what time of day, or what day it is etc. But returning home right after class is when you can continue the family quests.
