I believe I've made my final tweek before the deadline.
Develop games in your browser. Powerful, performant & highly capable.
Had nice FPS for that much particles and other effects.
Good job
p.s. info please about background warping
Interesting! Didn´t expect such a good performance with so many particles and bullets. I´ll have to explore more the possibilities of C2.
