Particles - A particle-based sandbox

Particles - A particle-based sandbox is a particle-based sandbox. It features:

-sand, which falls

-water, which flows

-a virus, which for some reason consumes sand and water

-glass, which doesn't get affected by the virus

-fire, which is warm

-propane fire, which is warmer

-something boomy, which may go boom

The simulation can be paused by pressing space. Heat sight can be toggled using tab, but this is still very experimental and I personally don't like using it. Brush size can be increased or decreased by scrolling. Elements can be erased using right-click.
