The list of items that you purchase from NES is taking what 50 pixels in height. You have to pixel pick where it is scrollable. Then it’s clickable space is poorly designed too.
Zero UX, very customer unfriendly.
I propose to extract items purchased to a separate panel, when there are > 1 item, to the right where it will be clearly visible what you buy.
Item | list
description | of items
Clicking on the item should preview it . Easy and simple.
It’s very unusual that such a valuable feature in-game is SO poorly implemented.
