Nicely incorporated the theme. I like that you start as a butterfly :)
Little bug: The motorcycle in level 2 does not seem to have a "destroyed" state.
3 suggestions (if i may! :)
- Maybe you could deactivate the collision on destroyed objects?
- You could include a random control influence: it feels a bit too controlled for a tornado. It could be fun to have a tornado that is difficult to control at first, always moving/floating a bit around. Then, when you progress you get more control. Right now, it feels a bit static.
- Adding moving targets could be nice too.
Music is good, menu responsive
