Poor..
The game was simple and lacked in just about every department.
First of all it was multiplayer. If you're going to submit a game like this either make it online multiplayer, which would be a lot more work, or code up some AI so that you can play single player. Hardly anyone comes on NG with their best friend by their side looking for a game to play together.
Secondly, if they did I'm sure they'd be very disappointed with this. It was simply moving up and down and pressing a key to fire either a bullet or a rocket. Nothing fun about it. As well as the fact that bullets moved with the character which sort of defeated the whole object of the game. Attach the bullets and rockets dynamically rather than animating their movement. That way you can make it so they don't move with the character, and you can fire more than one at a time.
On top of all this, the graphics needed a lot of work, obviously as at the moment they were just simple shapes with no shading or anything. Work on an AI system and some graphics and you might have an alright game ;)
Good Luck.
