These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Awesome Music: The music in this series is very beautiful and sets the mood of the game very well. The Collectors Edition of Dark Flight actually allows you to listen to the soundtrack on its own.
Funny Moments: In The Painted Tower, when you're helping the magicians set up the play, at one point you have to set up the hero with three items so that the play will be a success. Giving him the wrong items can get frustrating, but at the same time it's quite funny. Have him draw the sword against the princess. Go on, do it.
Tastes Like Diabetes: Several of Iris's and the boy's painted worlds clearly were this, at least until the villains took over. The mural in the children's area of the Library and the Garden world are particularly saccharine.
Right after you complete the play in The Painted Tower, the tower's gradual collapsing causes that particular painting to be destroyed, so that you can't visit it again and the delightful characters inside are possibly lost forever.
Franklin's statue breaking in Dark Flight. He can still be saved and it doesn't affect how helpful he is in the slightest, but it was rather upsetting anyway.
