Johnny Kung Fu (3DS): Floors 31 & 32 (Final Boss)

Hints: -If you're frustrated at running out of time, don't continue when you run out of lives. Instead, return to the title screen. If "Continue" does not show up on the main menu, start a bonus game and exit. The "Continue" option should appear and you can continue from the most recent "Game & Watch" styled floor you left off from with the amount of time you had left when you first played that floor. -The final boss is the agent that commands the helicopter to swoop across the screen and shoot at you. The agent will jump to the side of the screen opposite from where the helicopter will appear. He is invincible unless he is stunned. To stun him, use the Down + A move to throw one of the other enemies into him. Then, quickly attack the agent before he recovers. Precise timing is required to jump through the stream of bullets shot at you by the helicopter, but as long as you have lives remaining and you don't get hit by anything else, you should be able to survive. (SPOILERS) -By beating the game you will unlock the "Hardcore Mode" option (when enabled, you will not get extra lives after each floor and you can't continue) and "Master" mode (apparently a harder version of the main game).
