Nice work! I feel like the game was a bit too hard though. Then again, it took me a bit to realize that I can switch between the twins, so I played for quite a bit, and my solution to Level 2 was probably a bit different than intended lol. Also, on some earlier levels as the boy, I could jump off the girl's head (even if she was also in the air); but later stages, that became impossible. I'm not sure why. It might be a bug, so you may want to check that out.
Good game!
