I was pretty pulled into this at first. I will say that I didn't like it as much as I thought I would. I seemed to run out of ammo. I don't know, that's just something I don't want in a video game. I admit that the graphics are fairly well done.
I just could not destroy those green spaceships. I'm thinking they might be invincible. I really like the background with the blimps and all the firing going on. It doesn't affect the game much, but it sure is nice to look at. All the details are important.
