Playtest Update One

FISH.OS Playtest · published 9 Sep 2026, 23:56 UTC

All newsPlayers around this dateRead on Steam

I mentioned a mega update, this acutally isn't it. There's some things here that need to be tested before that can proceed. If leaderboards work well and look good we'll be good to go.

Interface Scale


Display Properties has an Interface Scale setting now, at 1x, 1.25x, 1.5x and 2x. Everything scales with it: icons, windows, text, the taskbar. It only offers the sizes your monitor has room for, so it will not let you pick one that pushes windows off the screen.

Five of you asked for this during the September playtest, most of you on large or ultrawide monitors where the fixed size read as tiny. Thank you for being specific about it.

Leaderboards


There is a new app on the desktop with four boards, running on Steam: Species Collected, Prestige Level, Achievements, and Time Played. I will be adding more.

Species Collected counts species you have found, not fish you are currently holding, so selling, fusing and recycling never cost you anything on it.

Your scores post on their own every couple of minutes while you play. You do not have to do anything. With Steam closed the game runs exactly as it always has, and the window tells you the scores are offline instead of showing you an empty board.

The Net

There is a browser on the desktop now.

Five sites live behind it currently. The Fish Cam has three channels, one of which fell over and stayed that way. Bubble Wrap is a sheet of packing bubbles you can pop, by click or by dragging across a run, with a Start Over button for when you flatten the whole sheet. The Fish Calculator does real arithmetic plus one button that does not belong there. The Fish Therapist listens to whatever you type and steers every reply back toward water. Fish Facts opens on a real fact about fish, and the facts stop being true if you keep asking.

None of them pay out anything. This app is more a platform that gives me flexibility on adding new content that doesn't need a full app. Community art gallery, puzzles and more.

Fixes

  • The tutorial could not be finished. It's fixed.
  • The fleet stopped parking in a row along the bottom of the water.
  • Rod and Gear is now a list with a detail panel, the same shape as the Fleet window, with a colour and level pips for each rod.
  • Coin chests are gone from the catch on every tier, and there is a short suspense beat before a reveal now.
  • Flippy greets you when you come back after a while.
  • F9 takes a screenshot of the window and writes it to Documents/FISH.OS/screenshots.
  • A window taller than the desktop had no way to scroll, so whatever sat past the bottom edge simply could not be reached. This is fixed.
  • Master Volume moved the setting and nothing else while music was playing. It changes the volume straight away now.
  • The Fishpedia was not recording Epic, Legendary or Mythic catches at all, so its top three rarities stayed blank no matter what you landed. It records them now. Anything you catch from here on will register, though fish you already caught before this build will not fill themselves in, so a species you are missing needs one more catch.
  • That also unlocks the last five TunaPlayer albums and the 200 species achievement, both of which were sitting behind a counter that could never get high enough.
  • Price Is Pretty Good Rn could not be earned by anyone. Selling above 2.90 now counts.
  • Two achievements asked you to own boat skins. These are removed.
