Hellicopter like game

I love the hellicopter game, so i made my own version. Check it out and tell me if you think its good and what could be improved. It can be kinda laggy some times, im not realy sure how to improve that. I know the speed you fly at and accelerate up and down is way out of wack compared to the normal hellicopter game but thats cause i like it that way :stuck_out_tongue:
just takes some getting used to. So have fun, and remeber to tell me what you think or give it a rateing out of 10 lol.
