Particle Life

I got inspired to make this by some youtube videos and made this,

I made it in a day so don't expect too much, 
but you can:

1. Change the "viscosity" or "heat" of the simulation, not sure what exactly to call it
2. randomize the particles attraction to one another
3. Mutate the particles attraction, changes it more slowly and changes aren't as visible

The game is meant to be player on PC with a mouse or track pad.
There is no controller support.
