I will be demoing Scribble Defense during GDC, but for those who won't be at GDC to see the game I posted up a video of the Build that I will be showing off. Here are the following changes since the last video:

1. Added tower placement UI, the towers are not hard coded to specific keys/buttons anymore and now are handled through the new UI
2. Added support for up to 3 separate creep paths. Creeps can come from all over the place! :)
3. Added a Area of Effect Tower that can harm all creeps within its range. Good for whittling down enemy health en masse
4. More tower/creep specific animations
5. Added support for high scores
