-No sound options
-ran to bathroom the first morning and blocked the door, sister got stuck trying to get in and softlocked the game
-you can just go in and out of bathroom during her shower for some reason
-why would you make people actually do math? add a skip
-quest markers take a long time to appear. I was already halfway across the house a few times before the item (that I already tried) becomes a quest item.
-if you pick the bad ending, the key is both in your possession and still in the cabinet. You cannot grab the key again, but you can go in the door.
-no meaningful choices
-tons of grammar errors
-my dead cat walks faster than sister does
-no text/scene skip/fastforward
-no info/menu for controls/hotkeys
It's obviously early early development, but you're still presenting it to the public. You should polish some of the functional annoyances, like the door, walk speed, adding a 'skip' to math test, text/scene skip, no controls info/menu. The art looks good and the story direction looks fine. The annoyances are taking away from the experience. I'm looking forward to how you progress.
