I think I found an error in the tips. When you're trying to help Nefari with her water issue (around level 13), it says to talk to her in the afternoon when the event requires that you talk to her in the morning. You might also want to make it say something different after the player finishes getting advice from the swimmers.
Overall though, this is a great game! I had a lot of fun with it! You should be able to invite Jade to spend the night with you! I look forward to future updates!
