What is the answer for lisa's puzzles? Or how can i get it?(I'm asking about in the main game not in the spinoff)
Lisa has 4 puzzles, but only two of them a are real puzzles.
The most obvious is the note you find in the kitchen with a cipher on it. This is the one that gates the suitcase. You can ask many characters about it, but Haily will tell you the solution if you ask her.
The second real puzzle is the series of word riddles, this gates practically nothing and is just for fun.
