You are right, i'll try something like sprite pooling for particles or
something similar.

The collision detection is a simple bounding spheres method using
square distances, I don't think that building a quadtree would be much
faster but I'll give it a try too when i have some time

Aniway, i believe that particles are what are making the whole thing
lag and they aren't counted for collisions, so i'll check the particle
updating methods
