I really liked it! It was a short but interesting experience. At the beggining, I was totally confused, but I understood your idea the more I went into it and when I started reading the log.
I really like the look of Adam's Bitsy, and you used it really well.
I think there is not that much things to do with this kind of ideas unless you make it like Kingdom Hearts and just embrace the "no stage is related to the one before nor the one next", but I recalled my times as a kid playing with my toys and creating worlds in my head, Smash Bros-ish.
Good little game, I hope you make more like this in the future.
