Particle effects

I am adding particle effects left and right. They have to be the cheapest way (in a Cocos2d game) to add visual appeal for the programming effort.

I also found out that a 1024x1024 PVRTC 4bpp texture makes the simulator run at 30fps, but the 3gs still runs at a totally smooth 60fps.

I think the hardest part of iPhone development is never having the assurance that you're going to sell enough copies to make it all worthwhile. Sigh...
