i don't think this game quailfy as a sandbox, there's one main story that you are forced to follow (minor change can happen but they are just flavor text and have mostly no impact at the moment)
in the line of the indicator for the time of day (i' even say week aslo ^^), a notification for gain and loss of money and a calendar for the bill and timed event would be a nice confort for the player
those minor details aside as they are just confort and nitpicking, i like the game and would realy like to see how it evolve later, it make me think a bit to cohabitation but in more blunt, that other game was more about being sneaky when making your move while here it's more about hammering the mind of the mc till she get bent

... "smooth inuendo" intended
after thought, as i was speacking about confort, a changelog or a list of current event would be nice as sometime the grindy phase are too plain and last too long, making the player (at least me) wonder if there is an event after the grind ><
