Hey!
I bought your awesome plugin about a week ago and only yesterday i started playing around with it. But i encountered some problems and i need your help.You see my game is a paper2d project and i am having trouble understanding how to implement them in my game. Some of the particles render and appear on screen, others are invisible and in general those that render seem rather strange even if i rotate them towards my 2d plane.
Would you be kind enough to test them in the default paper2d example and explain to me how to properly use them in my game? Any tips and tricks for us 2d guys? 
Thanks in advance!
