Asteris - Sci-fi shoot-em-up game (GPL code & graphics)

Hi,

I started the Asteris game over starting from a Metroid Fusion demo I wrote and replaced everything with some nice GPL graphics.

There is a small room done, you can shoot and there are no enemies yet. The concept is also vague for me.

I put my GPL source code on http://erana.yellowcouch.org/java/ <-- Asteris entry
