This is the first content update for Sand in a Box. We're introducing new ways to control the simulation: [h2]Control the speed of the simulation:[/h2] [list] [*]Pause and draw in a world without the pressure of flowing time. [*]Run the simulation at different speeds: normal, 2x, and as fast as your CPU can handle. [/list] [h2]Rewind Time:[/h2] [list] [*]Press the rewind button to go back in time! [*]Experiment freely, now you can undo everything. [/list] [h2]Improvements to the simulation:[/h2] [list] [*] Plutonium can now melt. [*] Plutonium can become critical at very high temperatures. [*] Fixed bug that did not draw some pixels of Plant (and other particles with 'absorb' property) [/list] Please note: The rewind feature significantly reduces performance and requires additional RAM. You can disable it in settings.
