Hi renegader,
The program works pretty well. The result looks ok. But the code, well, a couple of things would make it easier for others to look at and easier for you to manage. One thing, if you reference and load bitmaps, objects, sounds, or any external media in your program, you should include it with your download. Not everyone has the media or may not have it in the same location as your program references, so that will keep people from even looking at your code (because they can't run it).
Structure:
This is quite important and many people have their owns ways of structuring their programs but there are a few general rules to follow that just make the code easier to read and easier for you to edit later on. If I were to say what the main problem with your program was, I would say structure.
You should check out TDK's tutorials that will help you with variables and structuring your code. You should read through the examples and ask questions on anything that doesn't quite make sense. Here's a link:

Enjoy your day.
