I got two of the three endings; all I need now is the true ending!
I already got two of them (those being the secret syrup combo and the fridge doors), but I just don't know what the last one is.
EDIT: I found a note in the cupboard about somebody's favorite boba order. By "everything you got", do they mean all of the fruit, jellies, and boba pearls? Also, who is this "me" the game is referring to? The cat?
