The Last Tinker: City of Colors certainly has some heartwarming moments:
Because of Koru, The Green Spirit was able to learn to stop fearing everything, and The Blue Spirit was able to become happy again.
The bond between Koru and Tap. They have always been best friends, and this is often evident in the way they interact with each other, and especially in the way Koru reacted when Bolzo punched Tap.
In the end, all the citizens learn to get along again, and The Purple Spirit even gets his own District.
