Brilliant.
I love the retro style of it, the music is awesome and the graphics are beautiful, some may disagree, but I love pixel drawings. It's like playing an old NES game or something. Did you do the all the art yourself coz the sprites look lifted from a real game, if you did draw them then that just shows how accurately you recreated a style! Also, it's tremendous fun, takes a while before it gets hard, but still compelling.
