[Programming] ~ Zero shooting ~ TEST

Hello people !
2 days ago I showed a little AS3 fragment on what I'm currently working... I'm pretty satisfied on the results that I get, but I have some lags on the tests.
That's why I turn to you for help, here is what I ask for : on this SWF file, you can control the ship with the arrow keys, and shoot with the X key.
If you want to shoot a charged shot, hold the shoot button for a few time, and release it when you want (like in the original game ).
I want to know if my SWF file runs smoothly for you, if you don't have lags, because it bothers me a bit... Thank you for your help  

By the way, as usual, tell me what you think

P.S : no enemies here I will put them later : my priority is to know if there is lags or not...
