If you go into your User Control Panel here at the forums you'll see along the left hand side an option to join/create Social Groups. Many developers doing testing here will create a private group and just invite the beta testers so the testers can communicate their findings freely without fear of giving too much away to those in the general public (like, in this game, perhaps discussing solutions for some of the harder puzzle levels which would be considered blatant spoilers if discussed in the general public forums of TA).
some screenshots of more challenging puzzle levels: The game will include 70 puzzle Levels and of course the addictive arcade mode in 3 variations. The Levels are arranged in chapters of 5 levels. You can always choose which level you want to play but you have to win all 5 levels of a chapter to unlock the next chapter. Every chapter has also its own open feint online highscore list.
