Got stuck in exactly the same place. I have to admit that I didn't want to try again because walking. Is. So. Slow. You have to backtrack a lot, and it gets tedious pretty quickly. In addition, changing the height of the waypoints for the character might be a good idea. Or, if that's not possible, choose the backgrounds accordingly. It looks a bit silly to just walk through the air. Sticking to one art style might work better, too. At the moment things look very random.
I like the story. Visiting all your friends and family at the end of a long life is a neat idea. And that you used your own engine is great!
