Decent game all around.
~ Animation/Graphics ~
The only complaint at all would be the organization of the menu. It looked like it was just thrown together and plopped right in the middle of the screen. In my opinion that could be organized much better and perhaps the text/font that you used could have been a bit bigger to be easier on people when they read it.
Other than that the controls worked fine, the animation was smooth and all around the graphics were decent. Nothing too great, but nothing bad by any means.
~ Story/Content ~
What a simple game, but what a wonderful game at the same time. I personally haven't seen too many games this simple, but yet fun and addicting. That being said it could use some better upgrades and more complex action, but not a bad start at all.
~ Audio ~
It does need audio and/or sound effects. When you get an upgrade you could have a simple sound effect, when you lose a life, when you fly, etc.. At the same time just search the audio portal here for some ambient stuff. I'm sure the search wouldn't be more than 5 or 10 minutes as there is some great stuff on the audio portal here.
~ Overall ~
A very simple, but effective game. Keep up the good work and congrats on getting sponsored.
