I am playing HoD from version 2.10 on beta 18. And I found a bug. So say you have this:
gFg
gLg
Where F represents a solid block, that has a Flag 7, Fairy flag on it. In Hero of Dreams, to replish your life you lean against the Flag 7 (from the south) even if it is unwalkable, and you will refill your hearts. It makes it look as if you have to walk up to the fairy statue to get hearts. It doesn't work like that anymore.
Fairy flag works but just not how it used too. So maybe, have a game flag to make this fix?
