Maybe anyone has ideas on a space shooter. It feels like asteroids clone: big but limited space, filled with asteroids and enemy ships you have to blast thru. widh different objectives: destruction, escape, etc. weapons like blasters, plazma balls, mines and AI controled extra ships to help you. maybe u have ideas? --- Keep it simple, stupid

There are a lot of asteroids-derivatives around, try having a look at some of these (there should be a bunch of them in the GD Showcase).

Here is what I have added to my sidescrolling space shooter game, now dont go stealing all this my demo will be on my site in a week but here is what is in it. Most are graphical changes, others are game play.

levels on planets, levels on leaving and entering a planets atmosphere, weather effects (rain, snow, fog etc..) one level you play part underwater, the main character is a mech so I added sword combat. Able to buy different parts for your mech, an actual story and characters that take part in the game play, abilities and magic, and a lock on system.
