Awful game. It reseted 1 day after I installed it. I started again. Everything went well for the next 3 weeks. I didn't play this game for 24h and I click it and what? It reseted again. Not to 0 but I already had next station and it put me on 600th rank in the first one. I was 1000th rank in the 2nd one. I was logged on my google acc but it still didn't save itself. I lost so much progress. I gave it a chance but now I'm surely uninstalling it. It also takes a lot of battery.
