for the 12th boss, try to have at least 90 pirates (mine was 120) always go the opposite way. fire at the right side of the ships and it will be a piece of cake. (took down the boss with a melee fight but don't take melee fights way too long be sure to fire loads of cannon before engaging, then rinse and repeat) hard badge completed! :)
it's really great that you were able to 'recycle' the characters and monsters in a new kind of genre, good job this kind of shooter games are really what we need 5/5 for music. art and gameplay
this is my 1st game based on shootorials all art is mine, improved and added more codes, kindly take a look

one of the best spot the difference game but I do have to say I really didn't like the mirrored tree and the mirrored ink blot :| it was really just to test your eyes or to annoy but the other stages where really beautiful 5/5
