FincrementalOS is a hybrid incremental-fish-shooter and simulated operating system! Shoot down fish from the comfort of your submarine to collect and sell them on the market for money, then pour those funds back into your business to make more cash! Everything you need is easy to access in the built-in operating system, but configure carefully: The desktop is your window to the ocean, so the more windows you can see, the less fish you can shoot. Arrange your perfect desktop to optimize your fishing flow (Or just keep it all closed. Nothing’s stopping you)!

Combining the best parts of a punchy shooting gallery, number incrementing satisfaction, and fish collection and discovery, you use a massive submarine cannon to shoot down fish and collect them to sell on the market for profit. Use that profit to upgrade your submarine for more efficient collection, or put it into improving the ocean to uncover new types of fish and even new environments to go fishing in!

Everything you need to grow your fishing empire can be found on your submarine's built-in operating system. Open, close, and drag around the windows to your heart's content! But be careful: The only desktop you have is also your window to the open sea! Any spot a window covers is a spot you can’t shoot fish, so experiment, optimize, and create your own personalized perfect desktop to maximize your fishing flow.

Your OS has more than just business. Play a number of minigames that give unique effects ranging from paying out more money to granting consumable items that help you gather more fish! The more you can focus on at once, the more payout you’ll get. Your profits can also juice up these secondary games to make them even more profitable long-term. And maybe, if you poke around your OS enough, you’ll find out that there’s more to your submarine than meets the eye…

A number of minigames lie in wait within the submarine's computer, giving unique and powerful bonuses in exchange for your attention. Ranging from increased cash flow to consumable items, the yields are as good as the amount of time (and space) you give them. While you’re poking around the operating system and growing your fishing empire, you may also receive emails, which unravel the conspiracy behind the very submarine you’re piloting…
