I realy enjoyed playing the game and all in all it is a great level of difficulty, but I'm stuck at the one but last puzzle. This one is way to tricky to navigate compared to the other ones. I can not get passed all the force fields to turn them off. Saw the ending in a walktrough and I realy would have loved to get there so I realy miffed that I can't. A skip ahead to the next checkpoint would have been apreciated.
