Sounds like you've done just about everything so far =) There are two scenes with Caroline as well in case you missed them. Try exploring with her and taking some damage

who is caroline T_T, I forgot the real name, because I changed it all lol.
is she aunt of the hero? damn, i have waiting for this on the way then.
i have some tips maybe you can consider it, you should add horde (random or certain day) that attack hero house and wreck his garden and water containment, but you can prevent it more or less like a surprise encounter event and also game over if the horde enter the house, then the game should be more intense :v
Because... well, after create garden and water cont (the big one), its basically not survival again hehe.
