This is so good but I do have a huge problem that prevents me from progressing. I'm in the Biscotti tunnels and every time I exit them, the screen transitions to black and stays like this. I can move the characters around and interact with objects but I can't see anything. The screen is pure black besides the date on the bottom right.
This is truly a very nice and beautiful game and I'd like any help to be able to enjoy it more.
