Founded this my self it is a cool launch. You can not move in the air when you have been launched. But im pretty sure you can If you use the ball form some way.

This specific variant has been found by Neon if I'm not mistaken. It's not very useful as to get any sort of speedboost, you would need Roll and to even implement this in Any% you would need at least one charm which would lose more than this could save. This branch launch can get you to some very far places though including being an alternative method to skip the 3-key requirement
