I was able to take advantage of the weird friction by sticking to a wall until Drizit could fly around and get underneath. It's a wall-grab feature!
I didn't understand that Drizit could carry Klunk until I came and looked at the comments, but other than that I thought it was great! Being able to land on Klunk's head was a great solution to having to move multiple characters around the same area, which is an annoying part of similar games like The Lost Vikings and The Cave (Two games that I love).
I definitely think this could be fleshed out into a full game that would be excellent to play with a partner.
