Love the game! i played all the way through the demo and decided to buy immediately. Although I have a couple notes:
First off, I never got the scene of Masa taking you to the bar so it has just remained locked, although I'm not sure if its just unlocked much later than in the demo.
Second, in the Devil's Duel quest. losing to the demon froze the quest for me. going back again, the demon was there but I couldn't interact with it at all.
Lastly i got to the end of day 13, and when you wake up in the empty space i can move around, but cant interact with anything or get out of it so I'm just stuck. I don't know if this is a bug or if I'm doing something wrong?
