I'm African American and this is clearly the best subway/metro simulator for android. It took me about a month to learn how to properly operate these trains. You need to pay attention to your speed and avoid the emergency break. You need to anticipate how you stop ahead of the station and not in it. And these trains slow down going up a hill and speed up going down one. You do so much and the breaks are not that great so the challenge is to manipulate them way ahead of your stopping point to keep the train under control.
Why would you upload this shit? Try a few times, get used to the controlls, the breaking, practice a little until you know when to stop at the right time. Then you should upload to RU-vid ;))
