Quite good and i got 59 seconds! I would definatley give your game a 10 if you postwed it on AG. And I think the no music is quite a nice change for me. Also its nice and simple.
a good stratagy is to keep all of the bullets heading in the same direction.

(So that I don't spam the forums... all questions involving my game will go here.)

I've spent far too much time looking for music. I think I've found a good track though.

How does that sound?

NIce... sounds appropriate

Nice game, great job my record was 51 seconds.

well tryed the first and it was a great idea! then i tryed the second played it for a long (well not that long under a minute LOL) time and got this error:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at PlayScreen/onTick()
    at flash.utils::Timer/_timerDispatch()
    at flash.utils::Timer/tick()

i was runing the SWF in my debug flash player so it tells me istead of just contueing. but other than that the was  a big in prove ment on it mabye you could spice it up with some power ups and other bulites or enemys or say a system so you can turn intangable or stop time for a time but only once or something... or mybe you could put or spwan power ups that make it so you can eat bullits like in pac man! that would be fun and funny! or make it so you have to destroy the thing shuting at you anf then you go to the next level to a harder one, but that destorys the surival time idea...

all and all it is a awsome game i would give it right now a 8/10 (i am picky i know...)!
spice it up a little and i am sherh AG will take it in!

Yes, I know about the TypeError bug, and I have fixed it.

My idea currently is to have several "stages" of sorts. Each stage lasts for ~30 seconds, and once a stage is over, all the bullets disappear and something changes. Like the cannon fires faster or in shots of 3, or it moves around, or something...

Right, I've set up a website of sorts at a free web hosting service. The website right now is unfinished and is still under construction, because I'm not really that great with HTML. You can still have a look at it here if you so desire.
