Post your playable Crush the Castle 2 maps. There are other threads for talking about CtC2. If it's not good for shooting at or interesting to look at don't put it here: NO castles that fall apart by themselves, NO random junk piles.
what is it about my levels that determines the like ratio? - some have a high like ratio, some are really low and some are average
The easier ones to crush will always receive more likes than the ones that are harder to crush because the like button appears after you crush a castle. If people can't crush it, the like button won't pop up in front of them. That's why impossible castles receive no likes.
You can always like a castle from the people's empire too, but I don't think many people do that.
