I found this mildly entertaining flash game, based on Warcraft 3’s Element Tower Defence and Starcraft’s Turrent Defence. I haven’t played either of those so I have no idea how this compares but it’s a good diversion.

It’s pretty simple. Place towers, wait for invaders, watch towers hit invaders with variously coloured-blobs, upgrade towers for next wave. Repeat until castle walls breached.

There’s no pause or save feature. Don’t try to beat it unless you have a good twenty minutes to kill.
