Wow neat idea. I really like how polished the game looks. One issue I noticed I cannot scroll there, like the achievements are outside of my area and cannot do anything about it. Although UI is great
One thing I did not understand, when I do nothing my capital still grows :D So it's kinda you just wait for the capital to be very big, then buy one stock and sell it
Nice that you added sounds (and not just background music as I did ;) )
The game fits the jam theme perfectly, great job!
