@lordhershey, I did not want to make it too easy -- right now, you need to be within 5 pixels radius of the center of the station to be able to activate the gun. I do not knowwhat you mean by 'doing a wind up'.

Please leave any comment, questions and suggestions here. The source will be available after I am able to judge the likability of the game itself.

@jdf1234567, it was not my intention to edit the .java files. However, if I was to export it to a jar, I would not try to edit the .java file; but, instead create .txt or .dat files outside the jar that could be read back in.

Please leave any comments or suggestions. Oh, I forgot to mention that you can press the 'n' key to iterate through the stored maps (currently there are two).

@Diljot, would you mind if I built upon this? that is, to make something closer to the application itself where you can modify the world and then run it?
