Shantae and the Pirate's Curse

Once you have the scimitar, go to Spiderweb Island and use the downthrust on the zombies. Every time you hit the head, you'll get one gem. Since you can keep bouncing on their heads, you'll keep getting money until it dies, and since the zombies constantly respawn, you can keep doing this until you have as much as you need.

Collecting all 20 of the Dark Magic from the Cursed Cacklebats and then defeating the final boss will alter the cutscene upon defeating it, leading to the battle's second phase and a better ending scenario.

Once you have the boot, on the first dungeon on Saliva Island, in the first room, ram into the little steps. You'll be able to go through a level from the first Shantae game, including GBC graphics (some bits that are used elsewhere in the game will still be in the 3DS style)

Complete the game once with any ending to unlock Pirate Mode, then select it when starting a new game. Playing in Pirate Mode gives Shantae all of the Pirate Gear from the beginning, allowing for new shortcuts and faster clear-times.

Normally a long running space is needed to start a Boots Dash, this can be circumvented by using the circle pad and the d-pad in tandem.Start by moving the circle pad in one direction. Then press the d-pad in the opposite direction, letting go and pressing again as necessary.This will allow you to run in short spaces and execute Boots Dashes that were not intended, allowing you to sequence break the game heavily.

Clearing the game and meeting certain conditions will unlock bonus background artwork for the game's main menu.
