I love the game and everything, it's cool. But I just wish they could add 1 or more lines. Like line 10 for example it's my favorite one. Another thing I wish they could add is if they could add other sounds for the Metro if you know what I mean. There's only 3 lines and I just wish they could add 1 or more lines. Every 150 points is 1 ticket in game. So if they make another line the users could play the whole line and make more than 1 ticket so they could buy another metro or line.
