Let me be clear, I like the gameplay in this game. It’s fun. But there are two fatal flaws that have me deleting the game in frustration. First, I get login errors during startup - these can be canceled for a while, but after about a week on average the game just stalls on startup (during login) and you cannot proceed. The only remedy seems to be to delete and reinstall the game. After about 50 reinstalls, I’m done. Sent messages to the devs, and they’re telling me me to try a different internet connection - no questions about connection type, speed, error message, error log files, OS version, &c, anything they could use to diagnose a problem, and so I have to conclude that they have no interest or intention of diagnosing or fixing the problem. Secondly, every time they update the game, they make it harder and harder to progress in the game. New planes or plane upgrades that used to take hours or days are now entirely out of reach. To progress, you have to play their special events, watch for specials, or pay outrageous amounts of actual money. I’m willing ( and have) thrown a few bucks their way, but costs for a single plane, in its completely basic non-upgraded and so useless state, of almost $100? For a game on your phone? If you want anything new you have to stop playing the game and start gaming the play. No thanks.
