Really nice
I got that feeling of accomplishment from outsmarting a level when I made a really long cut at a strange angle. Previously I have gotten that kind of fun only from TIM (The Incredible Machine). I only wish there were more levels to master (took just over an hour and some luck to ace all 25 levels) and perhaps some more tools like a string cutter only for strings or an iron cutter that are limited (using a different counter) to bring some variation to the levels.
