The game suddenly crashed and I dont have choice but to restart the app but ended up losing credit score and unable to play rank game. So disappointing as I have just spent 5k for Soryu Maiden and the game will just pay me back by this kind of experience. Might consider to unistall the app since I might not be able to regain my credit score due to busy sched at work. It supposed to be a comfort plarform as escape from stress but ended up having more stress because of this. Waste of money.
