NOTE: The original design of this game works best with keyboard and mouse, but I don't know how to get that functionality to work on Scirra Arcade for whatever reason, so you can only use the gamepad to play this version. Elaborate controls can be found when you pause the game, and Navi will give you a briefing during the conversation on the very first stage.
