The wardrobe in your bedroom can often freeze your game when you try to use the full dress up function making you have to reload an earlier save as you cannot exit the wardrobe again. The quick menu outside works fine and for some reason also the pause/load menu when it otherwise freezes so it isn't game breaking but is annoying.
The new update appears to have somewhat broken character clothing with tears often appearing when they move. The ghosts also sometimes don't display their "copying your movements" act.
There seems to be food in the game you can't eat. There doesn't appear to be a recipe for cheese or fish despite them being in your fridge and I don't think you can eat them raw. Future updates may well expand the cooking system with more recipes/buffs though and the cooking/shopping for ingredients was surprisingly fun with some of the weekends when not at school spent preparing your meals for the next week to keep your stats topped off. Having the toilet stalls at school function like the one in your house for stat buffs along with the drinking fountains actually working to allow you to heal and stay healthy at school would also be nice from a gameplay perspective and give you something to do between classes other than just talk to people. Possibly also a cafeteria or vending machine to buy lunch though this could be avoided by making a packed lunch at home and bringing it with you.
They should sell milk at the Mall.
When working at the café and you go to get the order from the back room, if one of the other waitresses goes in as well you will keep on talking to her when you press interact instead of opening the menu to select what the customer ordered. They should stay out of that room while you are working or at least not be able to be talked to there so they don't get in the way.
It would be nice to be able to sort your inventory easier. Currently you have to drop items and then pick them up again in the order you want them to appear in your inventory which is very clumsy. The fridge has a sort of drag and drop system that works well enough if it can be used again. It would be nice to be able to close menus with the E key rather than the X key as it is more comfortably placed on the keyboard and you are doing it a lot. It would be nice to be able to refill the medicine cabinet in the bathroom with stuff from the shop after you have depleted it.
