A clever use of the theme, I love it.
It was also a bit nostalgic x). It reminded me of the old Kirby games.
I didn't make many combinations during my first playthrough, but it was a neat little game.
Perhaps you could add some kind of "trials" in the level where you have to a specific ability to continue, which would encourage the player to try out more combinations, instead of rushing to the end (which is currently a valid option).
Graphics-wise, the environment is a bit empty, but the style is pretty unique. The music is also really great.
Good job !
