Great! Nice visual touch on where you can grab. It really helps with understanding what to do.
A little be junky on controls but who I am to judge (appriciate feedback on my GMTK submission too).
Also, some squash and some sounds could provide some nice feedback (ala juice) which would make the whole experience much nicer.
Movement of the character a little bit too stiff for a rolling ball. I would expect it to roll for a little more even when I would stop pressing key.
Also, when move to your "tongue destination" it looks like the end of the tongue moves towards you.
And it would be nice to have a cursor hint when you're able to hit the surface and when it's too far.
