Great job. I love "manager" games, but miss something. Maybe someting that changes the gaame. Also, the prices changes too fast, so I cant change my route in time. But in general, a liked. Congrats!
You're right, of course! I think the I need to add more UI elements to give the player feedback on what's going on, and balance the dynamics of the economy better. I wondered if the game would be better with a rival trading company that you are "battling" against.
