There seems to be an error when you talk to Gratitude and ask how old she is:
While running game code:
File "game/script.rpy", line 1341, in script
N "Maybe this is a game of charades."
Exception: Sayer 'N' is not defined.
(I'm guessing it should've been a lowercase n?)
That aside, I think the story's pretty great! Especially with the bad endings, poor Bobo :(
