Conclusion: I bought this recently and although it didn't take too long to complete it, I loved it! There are many levels you progress through, meeting different aliens with differing skills along the way. The further through you go, the more of the aliens you need to call on to complete the puzzles. I found this completely addictive - hope there are more on the way!
Conclusion: In this game you play as five aliens (on a spaceship) and switch between them during levels and each alien has a special skill. each level is a puzzel, you have to figure out what goes where, what switches to press and what alien should be used. you cannot touch the lasers or the robots or the mines. after you collect all of the crystals you go to the green exit portal and the level is complete. (the blue portals only teleport you to somewhere else on the level).
