When Bowser dies at various points in Mario & Luigi: Bowser’s Inside Story, the brothers have to revive him by shooting adrenaline into his heart. Doing so leads him to get back up and become giant Bowser for a special mode that requires players to hold the DS sideways like a book. Suddenly, the game’s graphics play out across two adjacent vertical screens. Players use the system’s stylus to guide the King of the Koopas through danger. It’s a shame few other games in the DS or 3DS libraries have tried something similar.
