Help this cute little ship's captain to save her friend. There are a lot of impediments, so you must do everything that is required here. Just move forward and even swim! You can explore the sea and depth. If you are ready, then start it!
So, you begin the game as the ship's captain, determined to rescue the other people, presumably because lost all crew and passengers in an alternate dimension doesn't look real good on a resume, and you're going to need to get your hands dirty to do it. To control use the arrow keys to move, jump, and swim, while tapping space attacks, though the controls are completely customizable from the pause menu. Here each area is filled with coins and more to collect and baddies to wallop, and though some enemies can be taken down with a single whack, others will need more to bring them down. Good luck!
