Desktop Tower Defence: Rejiggered

Peeyow-peeyow-peeyow! The cutest ickle tower defence game, and the start of a PC-consuming trend, is back - this time with a 'Pro' suffix and a ton of new content. It's still as lo as fi gets, so don't go expecting DTD HD, but content-wise it's fatted with healthy new children. For instance, there's a new series of scenarios, and a sandbox mode in which you can toggle settings to your obsessive heart's content. Again, no vast, sweeping changes, but what Pro does do is evolve a desktop toy into a big ol' game in its own right. Still browser-based, still free, still as a charming as a kitten in an Easter egg. Peeyow!
