For number one that makes a whole lot of sense considering the subtle hints in the game, but I won't pry-sometimes even heroes could use a vacation or saving themselves as much as it sounds peculiar.
I'm a little sad about the second since I don't know many friendly slime types, but it's your choice and you've tried. I attempted a class about making games and even with the right equipment my mind couldn't take it sad to say. I didn't have the patience for the job. T__T
The last one is very helpful though I may have to be cautious since there are limits compared to a standard RPG but I'm grateful all the same; I was busy with earning money and getting stronger that I completely forgot about accessories. O_o
