very nice dramatic shadows, always a big fan of those.
the only bit of valuable feedback would be to consider changing the default controls. having 4 keys to pick up items seems like massive overkill. what about some system like {Movement key Left] + [Interact key] would cause the Left Interact to occur. or if it's a desktop only game, [Interact key] would use the Interact Action closes to the position of the mouse, or so on.
good work otherwise, keep it up
