There's an interesting idea here with the switching between dog and human. There seemed to be a puzzle with the books that I got to the end without ever solving. Presumably it opens the trapdoor? But I never got in there. Definitely a solid attempt for your first jam game. Also I disagree with some others about the movement speed. I think the movement speed feels good as it is, and the environment is not very big at all. Run exists to move faster anyway.
