There's this movie that I watched when I was really young, and I can't remember much other than it was animated, but very simply animated, where the main character was a stick figure. There was no dialogue, only music, and the backdrop was black while the buildings and the characters were very simple. The city is underground, and the main character is trying to get up to the surface, and at the end he makes it and sees the sunrise for the first time. I'm not sure what exactly happened, or if anyone else knows of this movie, but you never know, so suggestions?
