A good start...
This looks like it could've developed into a fun and exciting hack and slash game, but it's far from complete. There really wasn't any challenge to it and the "to be continued" nature of it after the first level made it seem really rushed.
Again, this wasn't a bad game, but it's far from complete and I really kind of expected more from a great programmer like you, Tom. Hopefully this gets a sequel with more levels, better graphics, and some actual challenge. I'd love to see this become as big as Pico.
