Doesn't the word puzzle gate the suitcase under the bed?
Also, I spoke to the character for help, but I am still stuck on the Word puzzle (and as such the code to the suitcase). Do you have any other tips here?
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.
