Playing with sand

It's fun just to watch sand fall, and even adults can enjoy the childlike fun of playing with sand with this app!
By tracing the screen you can build walls of sand, and make holes in the walls.
How you play is up to you! Find the different ways to play!


[How to play]
・Sand comes out from the bottle up top.
• You can drag the bottle to move it.
• If you let the sand fall into the mouth of the bottle below, it will fill up with sand.
• If you press the "Erase", your sand and walls will disappear.
• If you press "Reset" in the menu, your walls and sand will disappear, and the position of the bottle will reset.


※ This app is not aiming to replicate the actual movement of sand or the look of a sandbox. Please don't say, "This is not a real sandbox!"
