A nice effort but...
The maze game is a very common concept for a game idea. I myself have used it for many other submissions.
However since it's used so commonly you need to spice it up a bit. Maybe have some different features instead of just getting to the end of the maze.
Maybe add in some rotating windmills or moving objects that need to be avoided.
Also please never use the flash built in preset gradient colours such as the red and black circular gradiant, it makes your graphics look tacky.
Another way you could build on the game is to have a mute button or more music as the loud blaring music can get very annoying.
And last but not least when you submit a game try to give it some sort of replay value, your game kept me occupied for about 1 minute because it was very short with only 3 levels and sadly not very challenging.
Add in some more levels and objects and some different music and you have an enjoyable game.
i know i'm sounding very harsh but im only trying to point out the facts as i was making these types of games a couple of months ago and now i've improved a lot.
Don't get disheartned by this review though; keep working and persevere and you will improve.
Check out my Mouse avoider game if you want. It's called adventurea
Good luck with your future submissions.
