Hi. This was nice. I enjoyed playing it. Although a bug prevented a chest to close and I had to quit the game losing my progress :-(
Given time and polishing, it may become really good. I do not know if you plan on continuing, or what exactly you have in mind, but you might want to include some minor tweaks like: the buttons remain pressed for example even if the mouse moves away, when in town to train, it says zero funds, although when trading it shows the funds and they increase/decrease. I also suspect you plan to include graphics for the missing items :-)
It was not clear at the beginning that when opening a chest you could switch between the party characters and actually move stuff from one another, but it is a great feature and the inventory system is pretty neat. Observation: When you move an item to equip it, it goes behind the slot until you place it in it, losing the item visibility for a while.
