Generic at best...
Essentially the game is another generic platformer.
The graphic design seemed really lazy, as if you created various shapes freehand using the pencil tool.
The level design was equally poor... The game was overly simple with little innovation as you went along, to be frank it was a cake walk.
Even with a basic knowledge of actionscript you could have added some elements that would have made the game more unique. Such as masks, and puzzle based levels.
The menu design was obscene, you should have used the text tool to write out the options. I think it's important to keep in mind that first impressions are extremely important.
The first thing someone playing a game sees is the menu, if it's shitty there is a great temptation to close the game and hit the dreaded "blam this piece of crap button"
The music was alright, but after reaching the end seemed to go into a double loop,
and there was one level where it stopped completely this again is an example of shoddy actionscripting.
I feel for your next attempt perhaps you should take more time in the graphic, and level design. And also check for collision problems as there were quite a few I found in this game.
You may also want to consider checking out the game PIXEL on the portal,
it was made using very basic actionscript/graphics but still managed to be challenging.
Hopefully it may serve as a source of inspiration...
