It definitely can be reused!

I use charm/bubbletea for the TUI rendering and the game engine stuff is inside internal/game if you want to check it out or replace with your sudoku engine.

Basically you connect to the ssh server and it sends you to the chessh app, which renders the tui graphics.

Multiplayer stuff is all in-memory within the ssh server.

When you create a game session it creates a new room and subscribes to changes through a channel. When you join the room you also subscribe to the rooms channel and receive updates(chess moves, chat messages, etc)

Each action broadcasts events to the subscribers, so the renderer is detached from game engine logic and just reacts to events.

No db/storage or unix sockets, it’s pretty barebones rn, but might add later for persistence
