Pretty fun.
It was a little bit hard on some of the really tight spots and corners, but not too bad. And i got confused when i died a few times cuz i didn't realize that the back of your string movesdifferently than the exact path you take, so blargh. lol.
I think it would be cooler if you added more color options, and an option to use a key board or mouse.
(also, for some reason when i changed the wall color, they didn't change, but the string did, so iono.)
