Very smooth, Pretty with slick sound effects. I want a bigger tunnel, and some more things going on, like maybe to have a ride-along 2nd player to gun stuff down, and powerups & stuff. For an "unbeatable tunnel obstacle course it has nice balance. I'd love to see your code, and understand how you came up with this balance.
My Ship is constantly getting stuck next to an attacker, as though they are entangled. Though I shoot and shoot and shoot, I con't break free, even though I try to back up. And mouse point & shoot is the correct form of input for this game, please change it.
Something's wrong! I'm supposed to be shooting a bug to death on the beach, but the background keeps changing to all the different locked areas, and I can only shoot it once, and the game stops responding altogether.
Jeez! There's a bug that makes it crash the flash player after playing 5 - 6 levels! Maybe he's not cleaning up used objects, or the code gets stuck in a loop. Maybe it's too heavy with glowing and half-transparent effects.
