OOK, Once I Owned a Kestrel, is now being revamped. Previously, it was to be released solely on iPhone and iPad. Now, iPhone, iPad, and other mobile devices are dropped and it will be primarily a desktop project. Welcome to the new OOK. Enjoy.
Completed most of the new particle system features:
Particles: RGBA start/end, size start/end, additive
Particle Groups: Specify particles and for each: count, angle, allowed variance, life, offset distance
Spawning now looks at particle groups to determine the particles it spawns.
