Nice looking XNA game for WP7. The demo is a bit unclear though. I can’t tell if the perspective changes are in-game or just editor functionality. If the former, that would be awesome!!! The artwork is a bit different too, kinda cartoonish. Supposed to include both single-player and multi-player modes. I wonder how they are going to implement multi-player in WP7 since the APIs provided only allow asynchronous gaming. Maybe you take turns setting up your towers and then see how many waves you both can survive? I think that could work. Or they could take the time and make their own implementation of real-time multiplayer gaming which would be nothing short of AWESOME!
