Artbased games are never good, sorry.
When you got more submissions then you're years old, somethings wrong. When you got 20+ submissions and still haven't learned the most basic stuff, somethings wrong. If I had a dime for every time I've said this: You've commited the number one flashn00b misstake :( Your HUD, it has selectable text. Nothing makes a game look more unprofessional. Even so, the text inside it is sometimes so big it won't fit and all you'll see is half the text (vertically).
To be honest I only played the first few levels of your game. One of the biggest problems was that is suffers from bad collision detection (because it's artbased), it generally fucks up the heros movement in a game where movement is crucial (about that, the AI was really poorly executed, there was no way you could really avoid being hit, so what it boiled down to was a click-as-fast-as-you-can-game). I suggest you grasp the concept of tiles (google for Tonypa's tutorials) and avoid hitTesting. Good luck on improving ;)
