I finally got this game it's so full of awesomeness that Onechanbara lacked.
Is there any where with a decant guide to when certain costumes unlock I hear different stuff like complete the game, clear dads high score, but no definite answers and what to do pacifically for each costume.
If I remember correctly, beating dad's high score unlocks the gallery items (Pictures, music, etc.). As for the costumes, you get a new one every time you advance a stage (I think), and just beat the game so you can buy the rest if you have enough coins.
