I read the description and there is actually something mentioned about it, which does not ignore the fact that this information should be in the game and best in the tutorial, If I don't know something, it's the game's fault, not mine
product prices are inconsistent, I don't know what the prices were in previous rounds, there is no graph or chart comparing the price from recent days, which is the biggest flaw in a trading game, it's like making a shooting game without guns.
