Desktop Tower Defense

I came across Desktop Tower Defense at http://www.handdrawngames.com/DesktopTD/Game3.asp while aimlessly roaming about - and have been stuck since.

Its a flash based game, with crude hand-drawn graphics, and it takes all of 2 minutes to see what is going on - little creeps are trying to cross the desktop, and the player needs to build a maze of towers to prevent them.

That said, its more addictive than the flowerpot throwing Jardinains several years back.
