First of all BEAUTIFUL game, i absolutely adored the graphics of the game. The audio was fine, but the real star of the show, imo was the art and gameplay itself.
Speaking of gameplay, it was really good given that we only had a week, this game has solid foundations of a shoot 'em up.
My only real gripe, is that of the controls. The controls were good and quick, but this would have even better with a keyboard config. [i am sorry if it sounded rude, but i like shoot 'em ups to have a keyboard config :P] Anyway, this is only my opinion and i won't let it affect the ratings.
TLDR; A really awesome little game with a cool working shield mechanics and killer graphics.
