Straight A
Awesome game, never saw something like it and it's mindbendingly hard at some points, wich i like. It's nice that you can make your own moving machine and even better that you can design a machine to do certain tasks!
However... Some things in the game are just TOO hard and take a whole hella lot of patience, continuously having to tweak things just a little bit and finding out what's wrong with your contraption takes a lot of time so not everyone will like it... But I do.
