I don't know what 666's problem is, but I played it fine from his link (I tested it in Opera, but he might be having problems playing in FF or IE, I'm not sure). Very fun game, and very addictive. You took the classic shooter, and turned it around, very nice! I just wish there were more levels, because I loved the game. The only thing I found awkard was that some parts of a level (such as part 3/5) were harder than previous parts. By this I mean, for example, part 3 would be easier than 2. Though I found this weird, it was almost a break sometimes lol. Overall though, I loved the game, and would give it a 5/5.
Oh yea, one last thing, I noticed that the missles (weapon 2) didn't deal too much damage, not as much as I thought they should have. Everything but the first weapon were kinda useless as well until later levels, but none-the-less, it was a very fun and addictive game, good job

This is definitely a game I'll add to my arcade.
