817 gold ! I am a lord merchant :tophat:
I really appreciated the mechanic of managing market value ! Maybe I'm made for the stock market...
The understanding curve is a bit steep, but you took the time to make a tutorial and that's amazing !
If you wanted to improve upon your game I would advise a more player-friendly UI with icons for each product and maybe a timer for when the market will change. Is it supposed to be random ? If so, it's great, I was always wandering if i had the time to buy and then resell or if the market change would fuck me up.
Overall, that's a great entry, bravo !
