I wanted to use openGL lines for lasers.
But how to make bigger lasers? How to make cool looking lasers?
One way is to call glLineWidth() and make the line thicker. But there are 3 downsides: not every graphics-card supports it, the ends of the line seem 'cutted' and it does look very 'flat'.

Here are the download-locations for the windows-version and the source-Code:

I will polish that game, get some music and fix all the bugs in some weeks from now, since there are exams to be written ahead... 
Its LD time! I have managed to get through roughly the half of my core features.
