Towers won't attack closest to goal. Also glitch where a creature appears in the top left corner behind the wall, leaving my snipers to ignore enemies onscreen and shoot blindly into the corner.
very easy, very boring. i played it all the way through anticipating a feature or something to make it interesting, but there's no significant difference between the levels, and there's no real challenge. just seems like a limited version of similar games. good luck getting people to pay $15
