It was alright...
It was pretty fun for a while till I got really pissed, just like some other people I would die even though no part of my string was near a wall, sometimes when I took a slow turn a certain points my string would hit a invisible wall, or when I would backtrack or turn around I would hit some invisible wall. But overall I found this ones controls to be a bit to weird for my taste, but I was able to deal with it till the Barracks level where I had some major problems (but still able to beat it after a while -_-).
Nice job on the levels and I'll be sure to play the next one you make.
