I was worried the "Mud" didn't stand out enough glad to hear it was working well!
Looking for more details on the controls, was it the controls of the tongue?
Thanks for feedback to make my game better!
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.
