It's okay...
Like el-syd said it needs sound and/or music. It's kinda boring without it. Also try improving on flash skills when you can.

Overall: 6.5/10
The concept can't get much simpler than this! There are plenty of weapons to chose from, all with different effects and animations. Some of them are more challenging than others, where you have to really time the weapon. It's just not just a click-and-kill type of game. Not that I know why we would want to kill friendly intergalactic visitors, but... it was a good play! Keep it up!

this was good for its time with some inspired deaths...
I guess it's alright.
you entitled this "Shoot Da Alien"
and that title fits perfectly
the game is a bit funny
but not remarkable
