Cute art and great choice of sound effects. Definitely a novel and interesting way to input controls to a game.
If only the boss just didn't heal or just very slowly, that i think is the only issue what makes this game frustrating. I got him almost dead only for him to walk up to the edge of the screen where he cannot be circled and then had to watch all my progress reset.
Still a very neat entry with a unique approach and a take on the theme i haven't seen elsewhere.
