Touch the screen to fly (or mouse click). Press the green button to toggle fly mode (or F), and hold the blue to activate boom!(or space) The goal is to get as far as possible. When out of fly mode, touch the screen to jump.
Aim for the windows, or use boom to protect yourself.
Restrictions: Don't fly too high, or you'll go out of bounds; the green bar is your fly energy; the blue bar is your boom energy. Notice: you can't exit fly mode while touching a building.
What is "BOOM"? Boom is like a force field of destruction, it will protect you from smashing into that space in-between the windows.
