I disliked the very beggining, because there was no interaction other then watching how you are supposed to do things... to me a good tutorial lets the player interact with the game (albeit in a controlled space) to know the gimmick. And the first 5 levels serve as a better tutorial than those cutscenes at the beggining.
Other than that I really liked the rest. The idea of the game was interesting, the execution was good and you always added some new aspect to it in a good pace. And the levels were clever, but because I had no ideai how many there were I just stopped at 26.
Overall it's a good game. Good job!
