Walkthrough/ FAQ for this game
I ordered the English/Korean version of this game and found it to be quite an awesome experience! The story is surprisingly engaging and unless your Japanese is very very good, I highly recommend the English/Korean or Chinese version. Though the game is mostly intuitive I found myself stuck in a few places. It is NOT always obvious how to advance the story and there is not a lot of info on the web about game hints/walkthroughs.

As Expected :)
I ordered this last month when it was on sale for $29.90, and it's quite a fun and relaxing title. The animations are great, and it's quite impressive in the underwater world. If you're a fan of games like flOw or Flower, I'd highly recommend this title.

it's rare genre
Yes, it's as written in play-asia.com. The game is in english. Although the manual is in korean, but don't worry the in-game tutorial provides you with enough info. The only down side is all interactions with other characters is represented by photos. No cg character or voice acting, it's quite shame considering usage of Bluray media. Anyway, that's not the point of this game. The deep sea explorations is remarkably rendered. Buying this game kind of saving hundreds of dollar of scuba diving experience. Last but not least, the background music and sound effect are great. They are so comforting. Get it while you can.

Really multilanguage
I buy Aquanaut's Holiday (English / Korean Version) because it is marked that it support Chinese, and it really does! As the Chinese version is already out of stock, this is a good chance for Asian (especially Chinese) to own one!

good game
not bad ,not great
this game is more like an educating game other than fun
so if u like to be educated about sea species then this game is for u and it has a really good graphic
