This is a very unconventional and intelligent implementation. I played it for over 1 hour already. Well, the last level took most of my time. Very cruel..... But the excitement of being able to beat it was so satisfying.
I think the overall game design is excellent, except for the last part, why the moving platformer reaches the spawn point is just a little frustrating (because I play 2151234x and had to fall down to reset the moving platformer).
The game mechanics have a very high potential to be commercialized, especially if can have 2 player options.
