Good concept and amazing colors.
One problem is that you don't get enough of a warning when things are about to spawn. If I'm hanging out near the middle of the screen, something will always spawn on top of me, so what I do is camp the top, usually shooting downwards and holding z. This makes it very luck-based, since I can't survive an INCOMING from above.
I got 54350 this way, although it didn't submit for some reason.
