Um..
Well, the actionscripting isn't too shabby (assuming some/most of it isn't stolen from a flashkit movie, as a lot is on this site). The problem is, you need to come up with a better application for it, or your scripting abilities in general. Trying to emulate a somewhat popular game is not what you want to do. Obviously, it will be compared to another version of the game (which, odds are, will be about 10X better or more fun).
The best possible thing you could do is come up with something entirely original. Ok, maybe not entirely... but, a NEW idea. It really isn't as hard a concept as it seems. Use your own judgement on what you would consider fun. Somehow I'm doubting this game would be the first thing to pop into anybody's head as a game they wished existed.
