Nice

Lets go through the Game in this review. Starting with the Title Itself. "Smiley Shooter" abit unoriginal for a name and there is so much space shooters on Newgrounds already, as there is with every other type of Genre.

Controls- Glad you used the Arrow keys instead of the WASD keys, although I think people might have a problem with that so you should make it more user friendly, allow the player to chos the controls.
Fire Button--> I have alot to say about this, It's possibly the worst button that you could pick for a fire button. Space with have been Ideal seeing how you didn't need it for anything else.

Enemies--> not well designed with the exception of the Troll Face, Awesome Face, The Saza boss snake thing and the Blue enemy.

Upgrades--> Very basic upgrades, I expected more to fly at me. I thought some more weapon upgrades would have been a very nice touch.

Design of Shooter--> Seeing how the worst drawn thing was the Space shooter ITSELF was a let down, how long did it take you to draw the Garbage? 1,2 5 seconds?

ADDICTING--> Heck yes! And I'll tell you why, most space shooters have a very small choice on enemies, While this one we had Trollfaces spilting into more! It made me laugh when I entered a storm of them Hence losing a life and the only weapon upgrade.

Tips--> Try to make more levels, try to get an artist for your games, Research the most user friendly controls. And why not add in some Medals and a scoreboard feature?

Overall, a very well made Mini Flash game

Alright

This Had no real "Original" gameplay and wasn't that fun either, I was simple clicking Targets and competing for the high score, The Graphics were alright but the game overall wasn't memorable and not that challenging,

5/10 For the "Average" flash
3/5 for being nice :)
