Absolutely terrible. This is the most formulaic bare-bones TD I can remember playing, and the gameplay is still off, not to mention the crappy in-game art and slow speed. I'm being generous with a 2/5 thanks to the music and additional art.
On the one hand I like the story, and I love the artwork, and I want to see the rest of it. On the other hand, it's just a tower defense game. It's not even a particularly good tower defense game.
