I would have given it a full score IF!
the cannon rounds would match the ones needed in the map, when i reached LV 12, the cannon rounds started to get litelarry fucked up. when i was nearing to complete the level it was impossible... i got 3 of those skeleton figures in row, and no skeletons around but plenty of others (0 misses until now) then the pirates start dropping to the water so theres nothing to do by then. oh well off to scoring, ill think about giving it another review when you fix that bug, since it doesnt give the honest picture of the game if you cant advance beyond certain point.
Graphics(8): Decent graphics with some effort put into it.
Style(6): Style is nice though its almost a straight copy from "Bust A Move" arcade game therefore its not so original as it seems.
Sounds(9): heres where your game is shining :) crystal clear and theme oriented music and sounds, not like those flashes with a sappy animation and some 240BPM techno on the background.
Interactivity(4): tried the game and the same bug occured 4/5 times between levels 12~15 therefore it will drop the score alot. fix it and i raise it.
Humor(7): shooting Pirates out of the sky :P and parrots while your at it, too bad i didnt get beyond the certain levels, would have liked to see what else is out there.
Overal(6): nothing too new to the Genre but its worth playing atleast for a dozen times just for the theme and sounds ;)
