There was a file included that lists what buttons do what, which I thought was clear, but I tend to play a lot of games made with RPG Maker so I thought it was obvious when it might not have been. The tables were split between 2 squares on a grid, so I thought it'd make more sense to be able to interact with the bit you hid under, rather than the other side of the desk. In hindsight, I probably should've just added the event to both sides of the desk lol. I'll see if I can add some darker outlines to some of the objects.
Thank you for your feedback!
