OMG!!! I finished the hard version of gnat attack! If you shake the muncher longer with the flies on the screen, the giant metal one will appear!! WARNING! HARD MODE IS REALLY HARD! Level one, gnats, bomb gnats! Level two, gnats, orange gnats, bomb gnats! Final, bomb gnats, 2 bosses!!! I you managed to beat hard mode, like me, you wilk get another cool Amiibo costume! It is worth trying hard mode!
