Not the worst thing ever....
.... but not the best either.
You need to first, take your time with making the graphics slightly better. I know if it is your first submission you will be excited and want to get in on Newgrounds as quick as you can. But don't. It will be much better if you take your time with it.
Secondly you need to check for spelling errors. There are some errors in there, be careful to read through everything again to check.
Finally, give it some sort of storyline. I know it is meant to be like a dig at Windows saying Linux is better, but some people might not understand. The storyline in this flash is a little vague and it would be better if you came up with an original idea and thought everything through. Like i said, take your time!
You did have a preloader and a replay button so that's good, you are using some basic actionscript!
