Really cool Game.
I Really like the Concept of the Game and its very fun to play the levels and finish them, but at the second Gas level i didnt knew how to move on, if i needed my partner, then it would have been better to let the enddoors shut on the level before that. But this doesnt make the Game any less good!
Overall its a very nice Game!
edit: i found the way to that level i was stuck, i was just a dummy
