## What it is
Telepathy is a simple, message-based TCP networking library written in pure C#, designed for MMO-scale multiplayer games. It uses framing to guarantee messages are received exactly as sent, with an allocation-free hot path and a minimal ~700-line codebase.

## Use cases
- build a multiplayer game server in C#
- handle thousands of concurrent TCP connections for an MMO
- send and receive framed messages reliably over TCP in Unity
- avoid garbage collection spikes in game networking code
- replace low-level socket code with a simple Connect/Send/Tick API
- network a Unity game with Mirror

## When to choose
- you need reliable, ordered TCP messaging for a multiplayer game
- you want a tiny, dependency-free, easy-to-audit networking library
- you are building with Unity or Mirror and need allocation-free networking
- you need to scale to thousands of concurrent connections

## When to avoid
- you need UDP for low-latency, loss-tolerant gameplay (e.g. fast-paced shooters)
- you need high-level features like serialization, RPCs, or state sync
- you are building non-game applications where async sockets or higher-level frameworks fit better
