Unusable for work. I bought the original Cinetracer many years ago, and the sole purpose for the creator is to have a Steam-funded game to do his own experiments on. I would not recommend buying it, unless you have some extra money to see what it is all about - but beware - the program can be changed overnight, saves won't work anymore, and the mechanics will be completely changed - without a reason, for the worse or just removed. A very frustrating experience.
