This was a neat discussion on the untold parts of the story. Get what you mean about having plans to give a game a major update/expansion and never getting around to it. I've learned to plan on making small improvements and getting those uploaded ASAP because if I wait to make major expansions to my game, I may never improve the game I did upload.
Glad to learn there is an explanation for the bigger dresses in the maid's closet. The mysterious dresses was the one point I felt had not gotten cleared up and it also explains the bedroom deficiency. (If step mom had Alle's room, step sisters the locked room and Alle off the kitchen, three is plenty.)
It also felt like a tiny bit of a leap to go from learning green paint was deadly to wondering if Alle had used it to kill her family. If Dona had been meant to visit and tell Rutile he was suspicious, that explains why the green paint was enough to decide to investigate.
