The Chopper电脑版

I have made this game very simple but challenging,which makes you addictive to the game.You are the pilot of this chopper and only you can control it.when you are flying loads of birds coming your way.You cannot let the helicopter hit the birds,If the chopper hit the bird the game is over.How to control the Chopper. ?Touch/tap so the chopper will fly,but you need to develop the skill that you can keep the chopper still and lift or bring down when necessary.To keep the chopper going up you can touch and hold the screen in mobiles or click and hold in desktops.I have started with very basic and soon i will get the game more harder and adventurous.
