I Don't think anyone has found this glitch before but this glitch will work on any level that has a bounce pad.

To setup the glitch you wanna place a bounce pad close to a ledge like so:










To perform this glitch you need to jump on a jump pad and right as you brush up against the top of the ledge you click jump again and you will get a pretty high boost.
This might take awhile to do as it is pretty difficult.

Here is a video of me performing it, as you can see I boost a second time of the ledge. I do not know what mechanic causes this but it would be interesting to further explore the movement of this game.

Thanks for reading!
