Piisu Inc. has released a free demo for Fish Them All!, an incremental fishing action game that challenges players to catch 100 million fish. Available on Steam for Windows and macOS, the demo offers approximately 30 to 40 minutes of gameplay ahead of the game’s participation in Steam Next Fest, beginning October 19, 2026.
The demo supports 14 languages, including English, Japanese, Simplified Chinese, and Traditional Chinese. Steam Deck compatibility has also been confirmed, although the developer has not announced a release date or price for the full game.
Fish Them All! Combines Pixel Art Fishing With Incremental Progression
Fish Them All! centers on a straightforward gameplay cycle: catch fish, earn money, purchase upgrades, and increase fishing efficiency.
Players control a character aboard a boat, lowering fishing hooks into the water to collect fish. Each fishing session lasts 60 seconds, allowing players to make progress through short rounds.
Money earned from fishing can be invested in a skill tree that improves movement speed, hook size, and the number of fish caught simultaneously.
Skill Upgrades Turn Small Catches Into Massive Hauls
Players initially catch fish individually, but upgrades gradually increase their capacity to collect larger quantities. Eventually, a single fishing session can yield hundreds or even thousands of fish.
The demo introduces several abilities designed to accelerate progression, including a “Diver” that automatically catches fish and an “Explosion” ability that clears entire schools of fish with one button press.
These mechanics emphasize the incremental nature of the game, where each improvement contributes to faster earnings and increasingly substantial catches.
The free demo covers the opening portion of the full experience, giving players an opportunity to explore the core mechanics before purchasing the finished game.
Piisu Inc. is also collecting player feedback through a dedicated Steam Community discussion forum. The developer intends to use responses to refine gameplay and make improvements ahead of release.
Fish Them All! Joins Steam Next Fest on October 19
Fish Them All! is scheduled to participate in Steam Next Fest, Valve’s digital showcase featuring playable demos of upcoming PC games.
The October 2026 event runs from October 19 at 10 a.m. Pacific Time through October 26 at 10 a.m. Pacific Time.
Steam Next Fest provides players with opportunities to discover upcoming titles and try games before their official launches.
The Fish Them All! demo is already available, allowing interested players to begin fishing without waiting for the event.
Players can access the demo through the game’s Steam store page.
Full Game Targets 100 Million Fish in Four to Five Hours
Despite its enormous fishing objective, Fish Them All! is designed as a relatively short experience. According to Piisu Inc., completing the full game should take approximately four to five hours.
As players advance through the skill tree, additional technologies and abilities become available to increase their fishing capacity.
Drones, UFOs, and Unusual Sea Creatures Expand Gameplay
Later stages introduce automated fishing assistance from drones and UFOs, adding new ways to collect large numbers of fish.
Players will also encounter unusual marine creatures, including teleporting sea urchins, exceptionally fast squid, and enormous sharks.
These additions are intended to introduce variety as players work toward catching all 100 million fish.
Rather than relying on lengthy campaigns or complex objectives, the game focuses on a steadily decreasing fish population. Each successful catch brings players closer to completing the central challenge.
Piisu Inc. says particular attention has been given to pixel art, character animations, interface design, and gameplay pacing to create a polished experience within the relatively short completion time.
Japanese Character Franchise Funyamorake Expands Internationally
The game’s protagonist, Funya, is a jellyfish character from Funyamorake, an original Japanese character franchise owned by Piisu Inc.
Established in 2001, Funyamorake has appeared in Japanese mobile phone games, web content, smartphone titles, and other digital entertainment projects.
For more than two decades, the franchise’s presence has largely been limited to Japan.
Multilingual Demo Introduces Funya to Global Players
Fish Them All! represents the franchise’s first major effort to reach international audiences.
With support for 14 languages, the game is designed to appeal to players beyond Japan, including the United States and other English-speaking markets.
However, familiarity with Funyamorake is not required. The developer has designed Fish Them All! as a standalone experience that newcomers can enjoy without knowing the franchise’s history.
Free Fish Them All! Demo Available on Steam
The Fish Them All! demo is available for Windows and macOS, with Steam Deck support confirmed.
Although Piisu Inc. has not disclosed the full game’s launch date or pricing, the demo provides an early look at its fishing mechanics, automated upgrades, and pixel-art presentation.
With a projected completion time of four to five hours and an objective of catching 100 million fish, Fish Them All! aims to deliver a compact incremental gaming experience built around rapid progression and increasingly ambitious fishing challenges.
