-----------THIS ONLY APPLIES TO VERSION 1.0. IGNORE THIS IF YOU DOWNLOADED THE CURRENT VERSION-----------
ATTENTION (AND SPOILERS):
in the 2nd floor (Mr. Bob's house), in the hallway that leads to the 3rd floor, you're not supposed to outrun the mother before getting the blade of Zagaracathal, it's supposed to be a scripted event where you face her. If you did and then you saved on the 3rd floor, then that file is ruined. I'm uploading a fixed version so that you can't outrun the mother.
tl;dr: if you outrun the mother in the 2nd floor (Mr. Bob's house, near the end of the game) before getting the blade of Zagaracathal, DO NOT SAVE or you'll be screwed. I'll upload the fixed version right now (if you saved, discard that file)
