Yes, I am aware of both these problems and they have both been fixed. When I push the next update they will be corrected. I PERSONALLY fucked up the coding of the knife XD total beginner scrub error. The other is due to renpy being updated from 8.2 to 8.5. I understand that may sour your experience and I do apologize on that. It is extremely difficult to catch everything. :) So thanks for taking the time to actually respond with feedback. ^^
As for a game save. You are at the end basically. Only maybe 3 to 5 minutes left. I am sure their are saves floating around however. XD Also loved the response of the old lady and the cart. XD It was my version of a "quest" it didnt really needed to be done.
