If you click too fast, you end up stuck in fire mode until it runs out. When that happens, you can shift the elevators or even pause. Also, it's a bit short. Other than that, great game!
This game doesn't need a trading system, considering that there are 46 different cards. You can get all the cards from challenges. If you're really impatient, just buy the damn things.
Having the square on the right and the balance berm on the left messed me up. It's like trying to make you're left hand and right foot tap one beat and you're right hand a left food tap another.
