Just getting all level 1 casters and a guy with a shield and just casting like crazy worked just fine for me, until the last level I also needed an archer with crazy attack speed. Fun but a tad easy, and I agree with 348Joey.... you should really credit sounds, they were way too familiar to be coincidental
