I posted an early beta of this game a few months ago: https://news.ycombinator.com/item?id=48180924 - May 2026 (45 comments) and today released the full version.

You all gave extremely valuable and helpful feedback back then - thank you so much for that. It led to a lot of improvements:

* I reworked the onboarding tutorials multiple times for clarity, adding protections to stop players from shooting themselves in the foot

* I dropped the Comic Sans-reminiscent font and replaced it with Barlow Condensed

* I improved the layout of the dials for all screen sizes to keep players on top of things

* I added an "Angle-on-Bow recognition trainer" for practicing estimates of ship angles

For the full version, I fleshed out a full campaign with radio intelligence, patrol zones, and lots of historical events impacting things like which naval bases still exist, which types of missions are given, and how reliable your torpedoes are. (And just for fun, I added a full cribbage mini-game as well!)

Now, just minutes ago - almost exactly six months after I started development - I fully released Silent Shark on Steam (Windows, macOS, and Linux) and can't wait to see where things go from here. I have lots of ideas that could work well with this more map-centered approach.

The landing page is here => https://silentshark.app

I'd be really interested in whether you think the onboarding is clear enough now, and if you have related game ideas that might benefit from a more map-based UI.
