Nice idea! Beautiful art, too.
I would have liked the vines to be controlled each by a different button, possibly left and right mouse button instead of just the right one. It'd also be more challenging if the character was affected by gravity and you had to mind that while trying to go over things and letting go of where you've already grabbed.
Also, I spent a rather long time trying to understand what was wrong when I reached the pot and nothing happened... Until I let go with both vines. It'd be nice if you explained that somewhere xD
