Cast your line into the abyss to catch increasingly rare fish and unlock upgrades that deepen your ocean exploration. This short incremental game offers a relaxing progression system with minimal time commitment, though its linear skill tree and lack of endgame content may leave players seeking long-term depth wanting more.

What players are saying

▼ Not recommended 2 hrs
First 30 mins are fun but as you progress it gets quite boring because:

Linear Skill Tree
You don't get more powerful
Higher Tier fishes don't give more money when upgrading base fish value
...

When you finish the game (the skill tree) there is literally nothing. Not even an achievement?

A relaxing game with cheap price, cool upgrade mechanic, does not require you to spend a lot of time to progress, chilling music.
10/10 very recommend.
Still have a lot of room for growth so i looking forward to future update.
