Evol's Sandbox is a fun little particle simulator I made over the last few weeks. It's available for purchase now, though I marked it as in development while I continue to add on to it. You can create caverns, erode soil, plant seed, grow roots and flowers, add fire, add a bee colony, make a waterfall, and more. If you ever played the "falling sand" or "sand game" old flash games, you'll probably like this. I'm still adding to it, so if you have a good idea for a new particles (like rain or frogs) or some other cool feature, let me know. I wanted to release this before I felt it was done because I want to see what everyone thinks about its direction. Other particle simulators tend to have emphasis on explosions, and others on nature. I want to develop new features in the direction that most everyone is interested in.
