I think you mean to rotate on the z-axis.
The library is based on 2D so the particles are flat and do not rotate.
This could be done using the transformation matrix on Particles inside the draw method, but it is not currently implemented.

Can you able to suggest where exactly to change for transformation matrix on Particles system method.

As I said, in the draw method of Particle: https://github.com/plattysoft/Leonids/blob/master/LeonidsLib/src/main/java/com/plattysoft/leonids/Particle.java#L91
You have a Matrix, so you just have to apply the modification you want, it is likely that you want to do skew: https://developer.android.com/reference/android/graphics/Matrix.html#postSkew(float, float, float, float)
And then have the parameters to update with the rest of the variables inside update: https://github.com/plattysoft/Leonids/blob/master/LeonidsLib/src/main/java/com/plattysoft/leonids/Particle.java#L77

postSkew(float, float, float, float) , its not working fine. Any other way to do that animation.
