FISH.OS comes out Tuesday, November 10
If you're new here, FISH.OS is an idle fishing game made to look like an operating system from 1997. Fishing happens in a window, and so do the market, the aquarium, the fleet and a Minesweeper clone where the mines are sea urchins. You can minimize the whole thing and your boats keep fishing while you're gone.
What's in it
There are 250 species to catch and file in the Fishpedia, boats to send out on expeditions, an aquarium you decorate with your best catches, fish fusion, and a prestige tree for when you're ready to wipe the drive and start over with a bigger multiplier. Solitaire, Paint and a music player come installed too, along with 19 Steam achievements.
Wishlist it
If it's on your wishlist, Steam emails you the day it comes out. Wishlists are also a big part of how Steam decides who sees a game in its launch week, so adding it really does help a small studio like ours.
Giveaway
Closer to release we'll be giving away copies in Discord!
Thanks to everyone who played the playtest and the demo and sent us bug reports. A lot of the release build came straight out of those reports.
