I love the aesthetic and the music! I see in your note that you've already noticed that the game is quite difficult currently, but I really like the idea. I definitely think an indicator of how much you paid for an item would be useful (or at least an average if you bought on different days), as I found myself just selling stuff off and not knowing if I was actually making a profit.
The events really make the game interesting too, but it would've helped to see the result on the market a bit more easily.
Great job!
