Doodle Tower Wars

The fight of Handwritten Shapes!

Think smart and Draw suitable shapes in turn with your opponent.
Those shapes will stack up on top of each other until one of them fall down.
Try to make it difficult for your opponent to draw, but make sure your shapes still can hold on.
Once your shapes drop down, you'll lose the game.

Notice: The edges of each shape itself should meet each other.
And of course, be aware of your limited time when your turn comes!

Enjoy your match!
