Bought this on Steam yesterday, and basically lost 10 hours to it without realising it.
You run an item shop to pay off your father's debt from a fairy, buying and selling items that you would normally buy yourself if you were an adventurer in an RPG. Potions, Swords, Shields, Food, rare items, magical items.
It's difficult as hell, it was a Japanese game and just recently translated to English.
You also hire adventurers to go into dungeons, which are randomly generated, but you do get to control the adventurer so it does have an aspect of RPG to it, similar to Zelda's style of hack and slash more than anything else RPG.
It's fucking addictive, I have no idea how I lost 10 hours to it yesterday.
