F*cking impressing for your first flash game
Listen, normally I wouldn't give a game like this a 10/10, but when you take the fact in mind that this is your first flash game, it's totally worth a 10.
You made a nice old-fashioned arcade-style game. Of course, if you would have been a NG hero I wouldn't rate it so high, but, for the thousandth time, awesome for your first.
Tips:
A mute button. The music is nice at first, but gets annoying later.
If you're going to make more games, add things like wings, that move. Those things "top it off" you know.
Overall (taken in mind this is your first)
10/10
4/5
