In this game, the lines you draw become walls.
Use the walls you create to save people and cities from oncoming waves, magma, and enemies.

You can save your city and people by diverting the flowing liquid and stopping the flow.
If the lines you draw collide with each other, the game will be over, so be careful!

There are currently over 150 levels. Stay tuned to the end!
