NOTE: You SHOULD be able to click the piston button if it's overlapping something else (the mountain, another block, etc). This is a bug I thought I fixed, but apparently didn't. If it happens, reset the storm, move the piston plank somewhere else then back, and try again. That should hopefully fix it.

Protect your balloons from the storm!

Click on an object to move it around and click again to place it.
Scroll to rotate.

Keep your balloon birds from getting blown away in the storm.
You start with 50 birds. Preserve 40 through the 30-second storm to win.

Press start to face the storm.
Press reset to end the storm and go back to building.

THE STORM PLAYS OUT IN THE EXACT SAME WAY EVERY TIME.
The storm will drop more building blocks once upon hitting a certain time for the first time.

Fence  does not block lightning.
Wood does block lightning.
Press the button on the piston plank during the storm to extend it. It cannot be retracted until the storm is reset.
