The lenguage problem is something that i completely missed haha, and the money collection has a system that i now see that is difficult to inderstand without visual aid (chances that passenger get in or out are random, so is posible to collect nothing in stations at first)
lenguage, visual aids and a more friendly curve of stats at the beggining are things to pulish in the next update, i appreciate the feedback, its good to know that at least the main idea is appealing to the players, thanks!!
