Very nice take on the theme. I actually found myself getting stuck fairly often and thinking 'how on earth do I do this' before finally realizing the answer - and every time it felt extremely obvious once I noticed how to do it. Which to me is the sign of a good puzzle!
I did get stuck on the wall a few times while trying to glide past, especially as corners, I don't know if that was intended or just slightly funny collision detection.
That being said, really impressed with this idea. Finding something simple and making it into something great is a hard job, so well done!
