I had to force myself to stop play after 30 minutes, I couldn't even have it running in the background because I found myself going back to it to check if there were new things to sell! I like the graphics and the system worked well. I wish it would've been a tiny bit more obvious what everything did without having to hover over with the mouse. It took me a while to understand that I was supposed to press the click-button to get stones. I think I was looking for a more visual stone to press, maybe with a pickax as mouse pointer. All in all, I really enjoyed it. Great job!
