About
ARTDINK GAME LOG is a project to port and re-release game titles previously developed by ARTDINK onto modern gaming hardware.
It serves as a record (log) of ARTDINK's game development journey. By reviving past masterpieces using current technology and platforms, it delivers nostalgia and rediscovery to longtime fans, while offering an unprecedented experience to new players.
“Aquanaut's Holiday” is a simple 3D adventure game in which you explore a mysterious underwater world aboard a submarine. Released for the PlayStation™ in 1995, the game has no specific objectives to achieve. It can be considered a pioneer of free-roaming games designed simply to let players enjoy the environment.
You are an employee of the International Oceanographic Research Institute.
Having taken a vacation to rest your weary mind and body,
you set off on an underwater adventure aboard the state-of-the-art submarine “Holiday,” entrusted to you by your superior.

What you discover in the vast ocean is entirely up to you.
You can swim around without a care in the world, interact with the fish, or discover ancient ruins and let your imagination wander to civilizations of the past.
The underwater world is full of freedom and adventure.
Take on the challenge of mapping your assigned waters, and you’ll encounter familiar, adorable fish and strange creatures wherever you go.
Don’t forget to stack blocks to build artificial reefs.
As your artificial reefs grow, more marine life will visit the area.
Here, you’re sure to find a sense of peace you won’t find on the ground.
Relax and enjoy your holiday, letting your curiosity lead the way.

ARTDINK GAME LOG has added a “Remaster Mode.”
The textures of the aquatic creatures have been upgraded to high resolution, allowing you to admire their patterns and expressions in detail.
Of course, it also features a “Classic Mode” that lets you enjoy the game just as it was back then.
What’s more, by using screen filters like ‘Scanline’ and “CRT,” you can immerse yourself in the atmosphere of “those days” when you used to play.
The package also includes the original manual from that era, which explains the background story and how to enjoy the game.
Why not return once more to the beautiful underwater world that captivated you back then?

This was the first art game I remember playing. I was used to games with combat or death so at first I was terrified something bad would happen. Eventually I realized there wasn't anything to be afraid of in this game. This game became a comforting place for me. Sometimes I'd wander around and every time I'd find something interesting. For a while when I played it I would go park my submarine in some place with interesting music and just work or chill listening to it. This was one of the top games I wanted to see on steam. Imagine my surprise when days after launch absolutely no one has reviewed it. It's like I loved a musician, learned they're playing live, bought a ticket, and then no one else showed up. I can't help but find it a little sad. What I thought was an extremely famous game turned out to be a private garden just for me. I'm okay with that reality but I encourage you to try visiting too, especially if you love games like LSD or Yume Nikki. - Devs if you are reading this, please consider adding the english from the original PS1 to this game. The game is playable without it and I'm not sure it's financially viable to add it but it would make me really happy if you did. I know this not really selling makes the release of the PS3 Aquanaut's Holiday unlikely but please consider releasing that too. I never got to play that game and it's always been too expensive to buy so it would be nice if it were available.
なんとなくゲームしたいけどしたくないような疲れたときにピッタリ。何も考えたくないただただぼーっと海中を漂いたい方にオススメ。グラフィック時代相応の作りでとってもレトロ。海中のグラデーションの美しさが目を惹きます。時たまに流れてくる海中を思わせるアンビエントな曲が耳に心地よいです。ゲーム性が薄いゆえに、自身でどう味付けするかの腕前と想像力が試されます。ひたすら壁に沿って行く、ただ深く潜っては新たな道の領域への期待と一緒に潜航するなど。万人におすすめという訳でもないのですが、このページや動画を目にしてビビッと来た人にはぜひ。
子どもの頃に初代PSでずっと遊んでいたゲームでした!Steamで遊べるようになるとは思わず、とても嬉しいです。 海底をひたすら自由に散策するお散歩ゲームです。進めないといけないストーリーやノルマはなく、登場するのも魚とUFOだけで攻撃されることはありません。 基本的にはフラフラ潜ったり漁礁を作ったりしてのんびり遊べますが、真っ青で割と視界の狭いローポリグラフィック・遺跡とされるオブジェクトのチョイス(古代魚や人面岩など)・深海特有の不気味さが合わさって、落ち着く反面どこかで少し恐怖も覚えるような、仄暗くて不思議な面白さだと思います。 恐らくスタッフロールが流れる条件である漁礁の魚ゲージMAXまで進めましたが、地図の解放率は25%程度でした。マップがかなり広いです。まだ見つけられていない遺跡も多そう。 これからもゆっくりしたいな~と思った時に、ちょっとした気晴らしとして遊んでいこうと思います。 お気に入り: ・QUITを押した後の終了画面がおしゃれで素敵 ・ありえない速度で回転するマンボウとオウムガイ
For those who are wondering about the game only being in Japanese, the only Japanese text is in the main menu. Once you have gotten into the game all the text is in english. Also, if you aren't able to understand English, the text is pretty sparse and is relegated to the return-to-base menu, so it doesnt really influence the moment-to-moment exploration. So, if that doesn't bother you, try out the game! I hope this clarifies things a little bit about this PC port.
