Played in Linux (...x86_64 binary plus .pck file) and it worked fine.
The mines seemed static, despite my attempts to both collide with them and use the flamethrower on them. That's some crazy wind, but propeling the baloon with a flamethrower was nice.
I think I failed on explaining the movement system. You steer by changing altitude, and wind direction changes in a clockwise direction with altitude (this is actually how you steer hot air balloons)!
The little flag at the top of the balloon points in the direction of your current wind.
The big floating green arrow pointa to the next gate.
Sadly the flamethrower does not influence your position..
