I was having a lot of fun with this. I love the fact that you can drag multiple dragons and that they fly in the direction you throw them for a bit. Dragging them really hard to see them thrown off screen was a lot of visceral fun. As much as I liked it I couldn't bring myself to finish the game though because of the position of the mouse doesn't reset to the closest section of the border after going off screen. This caused some considerable frustration as the other dragons swarmed the plane because the mouse went off too far and the fact that you had to drag them really hard ended up compounding the effect.
If not for this grip I think you have a really solid game here and hope you can manage to fix it soon. Nice submission.
