Array/dictionary find improvements; Fast-forward particles; Lots of bug fixes.
"Particles: 'fast forward' action" - Very nice feature, but feels so it should been there from long time.
Something cooler would be array instead of "initXRandom
initYRandom" - so user can feed in array and spawn particles in differetnt shapes. Currently it's just dot, cone or random. So when tank is destroyed it's not the basic circle.
