In this game you get the chance to toast a toast with dynamite. Or you could switch on a light bulb with a baseball.
Basically, you have one or more elements which you have to destroy, move switch on or something similar. You are given a pile of seemingly useless parts and you have to build them together to achieve the goal.
The best thing about this game, however, is, that you can bulid your own experiments with hundreds of different elements like dynamite, rockets, balls, electrical power, laser guns, steam pipes, ropes and so on
I have been playing this game since 2008 and then bought it again on Steam to be able to get all the Steam exclusive DLCs. And I have to say, it was worth it. So get this game, if you have some money left.
