Sandfall
Draw a ledge, the sand obeys
Colored sand pours from spouts at the top of the screen, and every line you draw becomes a shelf it piles onto, slides down, and streams off. Route each stream into its matching jar, but your shelves erode under the flow, your ink is limited, and a stray stream contaminates the wrong jar with an ugly brown swirl.

How to play
- 1Drag to draw shelf lines, your ink meter is the budget.
- 2Route each colored stream into its matching jar; shelves erode as sand grinds over them.
- 3Fill every quota. Fans, acid pools and moving jars arrive as you climb.
What's in it
- Real cellular-automata falling sand with true angle-of-repose piles
- Jars fill in visible strata, the layers you poured stay layered
- Drawn shelves erode grain by grain, so every fix is temporary
- Contamination is recoverable but costs quota, a brown swirl marks the shame
- Fans that blow falling grains and acid pools that dissolve them
- Settled sand sleeps, keeping the whole simulation at 60fps on phones
