the biggest drawback i'm seeing is there doesn't seem to be any restrictions on attacking. so someone who has played since the start can attacking any new player(after protection).
We have that restriction, registration time difference between players in same cluster cannot be more than 7 days. In other words difference between "oldest" and "youngest" players is 7 days.
these are the lvls i was able to get an extra star on to complete the hard badge. world 1: lvls 2, 3, 8, 9, 10, and 12 world 2: lvls 3, 10, 11, 13. alot of it just has to do with luck so if you dont get it on the first try, keep at it.
