Paper Plane - What's next?

The game doesn't have insane amounts of downloads nor does it have lots of players, but anybody seeing this I'd love to hear feedback on what should come next!

This has been a project I've been working on for a while now and I want to take it a step further, but rather than just adding an infinite amount of levels I want to hear everybody and add things the community wants. So, if you have any ideas please leave a comment and you may just see your idea become real!
