Use your mouse to point the Mars helicopter and space bar to go up, relative to the helicopter's angle/direction. tilt the helicopter sideways or (recommended) diagonal and press space to move forward. point diagonal with space bar to go forward while countering the gravity, so you don't crash. every single level is possible, I tested all of them out. fullscreen is recomended for the best experience!!!
scroll down AFTER you complete the mission. There ARE in fact spoilers. warning: SPOILERS ahead!! this is my final request: DO NOT SCROLL DOWN UNLESS YOU FINISHED THE GAME!!! thanks to Benjamin for the hilarious "french penguin" that I implemented for nostalgic reasons.
