1. GAME is Glitchy. When selecting tiles on game it will refresh and your action was not applied. Happens too many times. 2. Game events countdown not reliable. Event count down states 1 Day 5 hours left. The event will terminate in 5 hours. 3. Game will show network not available when you have no connection issue. 4. The game forces you to buy gems as people will attack you while you sleep. 5. Messaging UX in the app is terrible, if you close your keyboard your message deleted.
