Cave Copter requires a delicate trigger finger. You're a helicopter traveling quickly through the cave and you can't touch the top or the ground or else you explode. You'll also encounter other small obstacles once you get a little farther. Use the left click button on the mouse to maneuver. You'll hold down the mouse button to ascend and release it to descend. Your score is measured by how far you're able to make it without crashing. It starts out a little tricky but before long you'll be getting into the hundreds and thousands of feet and hit a new level before you know it.
