Amazing, I especially liked the shop UI design! Here's some suggestions. First the "move" mechanics, I figured it it even exists after first playthrough, maybe there should be clear indicator it exists and how it works. Also for the moving, it's hard to see what are you moving until you put mouse on it, it's hard to visualize complete picture like that. Since there are some items which boost another depending on the position, that should be shown visually (like lasso shaped indicator).
