This game will be very hard for new player because you can be attacked by any lv. 50 anywhere with just 1 hit. And you will lose arround 4-7 mil credits because you can't repair you must build a new one. No way to leveling. So for dev, please find a way to help for low level to develop for example if attacked and destroyed by at least 5 level and up player the newbie can repair at reduce cost according to the level of the attacker. Maybe free if the attacker level 10 lv up
