New ideas at 24/9:
1. I think shopping options will added in a future version is good. Use your "point" to purchase somethings, unlock the new item when you level up.
2. Similar to the second point above, adding somethings such as blindfold, used for extend the duration stay inside the locker, things that affect the locker.
3. I know I needed to select a room before one day start, we can put shopping options in room selection interface, to purchase the item that only affect the current day only. Such as pajamas, only available in nurse room, used for make the girl sleep and won't awake, you can do anything you want on the bed all day.
