Very Interesting and Fun
Good things: Pixel art is always awesome. The abundance of paths added a lot of depth. Logging which paths you took at the end was neat. The 'storys' of each phase of the dragon's life were interesting.
Bad things: Not so much. Walking as the hero took too long and I usually skipped that part, especially when I set the dragon far away from the town.
Overall: The cool concept and unique style makes this a great flash game. Great job. :]
