@Akira: I adore those homing bullets too :-)
Thanks for your positive criticism. Glad I put out the demo already, this will make the game even better. I´m totally with you regarding the music – Adam Mortons soundtracks just drives the gameplay on and on and on. The audio effects are toned down already in the release version of the game, so the music gets more of the limelight. As for your comments regarding too many hitpoints on attackers: will see what I can do about that. It´s a matter of balance.
