EVERYONE, THIS GAME IS SHIT. Go play The Powder Toy, Completely free and downloadable. Just go to google, type in The powder toy and download it. It's WAY better than this. Footage- http://www.youtube.com/watch?v=dJ1HKPlQKrE It's the 3rd game on there.
Tip: on the very first level you can just book it to the totems A.K.A you build collectors leading right to the totems without building anything else but you need to be fast.
The only problem with this series of games is that it's too grid like. The ball only moves in cardinal directions and sometimes I can't get things to work. My suggestions are a hint button, different gamemodes, a level editor, and more peices like portals. I'm not saying it's a bad game, i'm just saying it could use some more content.
