My first ever open source project that I've made in 2021. Now that I've found it, why not publish it? :D (Code is garbage)
That's simple battleship LAN game with UI, and simple AI
To use: Download a release -> Open -> Open on another Windows device -> Multiplayer -> Decide who gonna host -> Let other player input host's internal IP address.
You can also play vs easy/mid/hard bots :)
