They should add the ability to run. :v I know the house is small and the rooms too, but it's a pain to go up and down stairs to get ahead in the day.
If you use the "A" and "W" or "W" and "D" keys to walk diagonally, the speeds add up. It increases the speed a little, but it worked for me.
I speak Spanish, so if something is misspelled, it's because I used the translator.
Oh that's right, I found a bug that gets me stuck behind the door to the little sister's room. If you're standing behind the door right where it opens, the door passes through you, preventing you from interacting with it and locking you out of the way.
I don't know if they fixed that in a paid update, maybe I don't know if it's available here, but it would be nice to fix it since I had to load my save :'v
