Dive into a beautiful yet deadly pixel deep sea and track unknown signals from the abyss. Manage oxygen, pressure, currents, and creatures while exploring. Capture life with a harpoon, find relics and chests, upgrade gear, and face hidden giants. The deeper you go, the greater the risk.

About

Begin your journey from the safety of shallow waters and descend through coral reefs, kelp zones, current-filled caves, and abyssal depths covered in dark mist. As you dive deeper, water pressure rises, oxygen steadily drains, and the creatures lurking below become increasingly dangerous.
An unknown signal awaits somewhere in the depths—but you must decide whether you are truly prepared to reach it.
The deeper you venture, the more valuable the resources become, but the longer and more dangerous the journey back will be.
Continue following the signal, and you may discover rare treasures, Abyss Rings, and hidden objectives. Turn back in time, and you can secure your rewards, strengthen your equipment, and prepare for the next expedition.
When your oxygen is nearly depleted, will you still dare to descend another hundred meters?
Use your harpoon to aim and capture creatures from different regions of the ocean. Ordinary fish may scatter and flee, predators will actively hunt you down, and the massive creatures lurking in the abyss require powerful equipment and careful strategies.
Capture creatures, open treasure chests, and recover deep-sea resources to earn Fish Coins, upgrade materials, and special equipment for future dives.
Manage your inventory and upgrade equipment at supply stations:
Increase oxygen capacity and dive endurance
Improve pressure resistance and survival ability
Enhance movement, harpoon range, and retrieval speed
Collect Abyss Rings with unique effects
Upgrade gear to unlock special passive abilities
Choose a safer setup focused on endurance, or sacrifice stability for greater combat power, capture efficiency, and deep-sea rewards.
Sudden schools of fish, oxygen leaks, abyssal resonance, and unknown gazes can completely change the rhythm of a dive. Currents push divers and creatures through the water, darkness limits visibility, and certain deep-sea events can turn familiar escape routes into deadly paths.
Follow the signal, challenge abyssal creatures, claim the core, and return alive before the final choice arrives.
In the deep sea, the greatest danger is not always the monsters—it is the thought of “just going a little deeper.”

[h1] 五分钟毕业,氧气先崩♥ [/h1] 下潜五分钟,打了几条鱼,钱多到能把所有升级直接拉满。一路游到最底层找目标,结果氧气耗尽了,不是没注意,是根本没意识到旁边没有氧气补给点了,下面还比较复杂,作者吸取建议增加了明显的闪烁提示,这态度确实不错。 氛围还是有的,黑漆漆的海底、珊瑚礁之间的穿行感,确实能让人屏住呼吸一小会儿。但作为动作冒险,战斗部分偏少,大部分时间是在跟氧气条搏斗。地图随机生成增加了点新鲜感,但地形来回就那几种,也不是很大,探索感很快就会消失。也就是“杀几分钟”的水平。等更新几轮再看吧。 [h1] 任狂客难招,采芳难赠,且自微吟。 -- 忆旧游·登蓬莱阁 张炎♥ [/h1]
Fun short game, The controls are simple. Really fast gameplay but gets tedious after the first 100 fish. At first didn't know how to regen oxygen or that there was a shop in the first 5 minutes until going near the blue things.
Only played for a few minutes and still managed to gather enough coins by harpooning fish to buy every single available upgrade and max them out. Swam down to deepest layer to search for the "abyss core" or whatever it is you're meant to recover to win. Ended up dying of oxygen deprivation because it was incredibly unclear how much oxygen I had remaining, or that it was even getting low. Had no desire to try again. I feel like this game offers little replayability anyhow, but for free it's OK for killing a few minutes. Only things I'd recommend improving/changing are making fish give fewer coins so you don't max out upgrades quite so quickly, and make it more obvious when you are about to run out of oxygen and drown (a beeping/alarm sound or something might work).
