Thanks for trying out the game even if its not the kind of game you would normally play. It is geared more towards the numbers driven side of RPGs.
UI/UX is something I struggle with the most of the things that I worked on, thanks for the feedback on that as it will help me further refine it. I'll send a message to the artist to let him know you liked the aesthetic, if he hasn't seen this already.
The trading was implemented, but the chests in the dungeon are still using a placeholder sprite so they don't really look like chests. You start with no money in the game so if you don't click on the chests that don't at all look like chests then you are just broke in game lol.
