Gree,
I think your players are pretty patient. About 1.5 years ago you promised a new building "Fountain of Youth" that gave Health Regeneration and it has never been released.
It would be nice to follow through. (I know this is a prayer and hail mary attempt) but thought I should bring it to your attention (assuming you still check the forums)
Not sure where the player appreciation thread went but the idea originated back in July 2014 and shortly after there was a month that the idea was submitted, Voted on and Won.
"-Fountain of Youth- Health Regeneration. "A man sacrifices his health in order to make money. Then he sacrifices his money to recuperate his health." Probably the most enticing potential new building in the game. A true gem and challenge that all can aspire to obtain. As such as the Red Light District This building will work in 2% increments for quicker for health Regen. (lvl 10 is 20%)"
