Hello, I quite like the work you have done on this, and I myself am creating a geometry wars style game for my IPT major this year. I would like a hand, if you would.
When creating the ripple effect, what did you use, a mask that is played over the top of the grid at the point where the enemy was killed, or something else?
The way you make the enemies follow the charachter, is it similar to making an object follow a mouse at a delayed speed? if not could you please post the code. (i would appreciate it if you could post it either way, I just can't find a way to implement it right : P)
Your tracer and particle effects, what technique did you use for this ??
If you could answer these questions, it would help me a great deal.
Thanks

Oh and good job on the movie as well 9/10 (I don't like mouse aiming :P)

Sorry I haven't read this before. Short answers for if you are still interested (or someone else is).
Ripple effect is made using AS3 filter DisplacementMapFilter.
Enemies following are made so that enemies have speed vector. This vector is corrected a bit towards the player in each frame. This makes enemies follow ship but not directly towards it if ship is moving.
The game consists of two overlapping bitmapdata objects with alpha enabled. Particles are drawn using copyPixels to top layer. So sprites in this game. I prefer drawing everything myself (works usually faster than display lists).
Oh, and I wouldn't suggest keyboard aiming. Having 8 keys that are used at a same time definitely causes problems on many keyboards as thay cannot handle too many simultaneus key presses.
