The game starts out brilliantly and rapidly devolves into a chore. To achieve true greatness you must make more variety/replayability. I was literally falling asleep during some of the marathon-like levels. Almost a great game; you must tweak it and improve it!!!
apparently there is a weakening of the bridge over time... really sucks to have to wait 5 minutes for your guys to complete the sequence only to have the last guy fall off the very last bridge... otherwise, fun. needs music!
