A Tower Defense game with a twist, scratch the baddies off the desktop using a pencil!

Fight your way through twenty levels, and unlock many new towers and find different ways to use your lethal pencil.

- Stop the waves of critters from finding the exit.
- Build towers and use your pencil to scratch / hover over the critters to damage them.
- As the game progresses you unlock new ways to use your pencil and new towers to build.

Hint: Enemy move slow at upcurve and fast at downcurve
