I went back and found another error that was initiated when I clicked on the shutter and pressed S to take a screenshot. I have the log for it. Hopefully I can message you it through Itchio.
I don't know if it's by design, but after Millie takes a shower, I patted her head and her clothes changed into the night set.
I've also seen that she keeps that on in the morning of Sunday instead of her daytime outfit. In another instance, she was wearing her day time set at night. Even after taking actions they don't change to the night set.
As for the Sprite animation, I'm not sure what the sprite set is supposed to transition to. It seemed fine for most actions.
In my opinion, I would switch out the S button to go back to being a screenshot key. and use another key for the inventory. I had to use my screenshot software to get this screenshot for you to see Millie's outfit not changing in the morning.
I also have to go through the entire intro and starting point before I can touch the load screen. Will there be a skip option in the update for that?
