@hopeful Will do! In it's current state, it's best for massive particle fields because emission isn't quite working right. And I was only able to get stretched particles by speed (a Shuriken feature) working in 2D. Both of these things can be fixed, but I'm still learning about all of this stuff for the GPU as I experiment. Lots of things are planned, and I'm currently limited most by my own lack of experience with GPGPU. A lot of this stuff would be easy if I was doing it on the CPU.
