Sand!

Based on the original "falling sand" game, this little time-waster lets you draw different elements and watch them interact. Set things on fire, grow a garden, create elaborate set-ups. Most elements can be set to either draw or emit by pressing again on the palette.

The interface is minimal to free up canvas space, but elements names are shown on selection and there are basic instructions and element descriptions when you press "?".

This game offers 27 elements, of which 17 can also emit (aka "spouts") by selecting them twice.

Reviews

Amazing in every way except...
B00BLEMAX

Filled with lots of interesting elements. Please add option to switch to landscape mode. Its uncomfortable to play in portrait, especially when you want to hold your device. Also lacks some features like speeding up or slowing down time and the pen size is limited.
