While the concept and execution are pretty top notch, the game seems to solve itself (given you don't lock any pieces into the wrong place). you'll find a later part of the sequence has worked into the proper position without you ever addressing it. Otherwise well done.
While a most excellent game, the final matches in the alien campaign need looked over. Somehow through killing themselves before i finish them, the AI prevents me from scoring while seemingly playing some shady numbers game. I hate when i hear this but 'this game might be smart enough to cheat'. Either that or it has read moneyball.
people need to stop the guide stuff... its not even good advice... bouncing at 6000 feet makes no sense because bouncing at any point is an inefficient loss of speed... its all about initial height and speed... go pretty high with your boosters, level out and reach a fast speed... wash rinse repeat just have fun and feel it out from there
