EDIT: I have it all figured out! It was NOT a bug, just a problem with the cbmformat adding extra data at the end of the disk!
With the extra data: When I take a nap and it's night time, if I leave the house the game freezes on a black screen with music playing and the disk light on.
Formatting the disk properly fixes the problem and I can leave the house.
Thanks so much for an amazing game! Looking forward to the cartridge!
Just an FYI, the sequence of events with the swan and the apogy fruit can be a little confusing: If you haven't yet talked to the swan but have the fruit (ie. you already know she wants the fruit) and then you bump into her—the exclamation mark appears—and you "use" the apogy fruit, it disappears from inventory. The swan says all of her first meeting dialogue, and nothing happens. Talking to her again, she reminds you to go find the fruit. If you look at your inventory, the fruit is back and can be "used" again. Then the swan is satisfied.
