Great writing, visuals and sound effects. Amazing music, I really liked the Garage background music. This game really brought the nostalgia for old console games.
The controls are very nice, and the fact that you've implemented the backwards walking is great. Good effort. Animations are nice too.
Moveable objects are (probably deliberately) made a bit more "pale" compared to non-moveable, which is a fun touch if is on purpose.
Suggestion: please, while interacting, make Spacebar not instantly skip the line of text, but finish it instead.
Sometimes text moves a bit too slow, or I skip the text accidentally.
Found possible error: while moving shelves you can trigger the animation while moving orthogonally to the pushing path.
Found this demo among others in Haunted PS1 Disc.
Great demo, can't wait for the updates.
