Deep story and very well implemented audio + music! I noticed you've already got something prepared to deal with the slow text, so my next best input from the perspective of a "game" would be to maybe provide some meaningful actions for the player? Even seemingly small tasks like helping the builder for abit to relive old times as friends could really spice up the perks of having interactions in an otherwise already beautiful side-scrolling storybook. Just my 2 cents!
