Well It's a very simple game. It has it's own difficulty but it doesn't have anything else to show for other than to click... then play the game.
Design is very simple and somewhat realistic but it isn't appealing to the eyes of the player. maybe it lacks more things other than fire and the nature? maybe add buildings and a background. Problem is it's just way too simple.
The game play functions is very clear and easy. And there's NOTHING more to it. Very basic with only the challenges of how to fly the helicopter fast and steadily.
Seriously you can add more to this. like a story. For example a boy accidentaly burned his car. Simple as that. Just the need for dialog.
No other features other than the gameplay itself makes it kinda boring as well.
