Fun to play at the start, now just boring as you can't progress as fast as the game would like, for example my radio tower is behind by 5 upgrades as batteries never appear in the world and its so hard to find the stuff you need to upgrade these buildings. Also, the storage capacity is rubbish, you should be allowed more than 30 slots in an upgrade especially at higher levels so it's constantly full. The game is just getting boring, everything is so slow to do as you never get the items you need
