Consecutive Fighting Boss Mode-If have you found every cat in the game so that your life gauge is full, finish the game and after the credits a 'cat-count' will appear. If you found all the cats, a new option will be available in the options menu just below the Sound Mode menu called Consecutive Fighting! Large Boss Mode. Enter this mode to play the four Impact scenarios against the bosses!
Avoid Projectiles-Here's a strange way to avoid an attack. Change characters just before a projectile attack reaches you, and it will pass right through you.
Exorcist Impact-At the end of the Impact cinema sequence, you can rotate Impact's head with the control stick. Wait until it shows Impact's full body with the yellow and orange stripes, and then use the control stick to turn his head Exorcist style!
Reappearing Items (Lots of Money)-If you find a room with a lot of gold (or pots with gold) such as the first room in Oedo Castle walk into the room and get the gold. Then leave and come back in and -- surprise! All of the gold is right back where it was! You can do this as many times as you want and stack up on cash.
Blade-Shield Usage-When Yae uses her blade-shield, she normally can't move. However, if you have the armor or shield and receive damage from an enemy when using the blade-shield, you can move.
Unchangeable Hair Color-In the middle of using Goemon's touch-and-go skills, get killed by an enemy (if you have more than one life). If you do this, you will come to life again with golden hair. However, if you want to change the character, you can't change the hair color.
