About this project

Host-authoritative co-op for game version 0.14.5 Hide & Seek runs (BepInEx 5 and MelonLoader builds that play together). Syncs players (directional sprites, names, pings), every named NPC and its abilities, doors, windows, notebooks, free pickups, teammates' item effects, Johnny's shop with a shared YTP wallet, elevator results, individual capture with teammate spectating, and LAN host migration. LAN over TCP, or online through the game's own Steamworks.NET (Steam lobbies, invites, Valve relay; no host migration there). Random events follow the host (fog, Mystery Room, ruler and time-out mirrored; others host-only); field trips get the same Pitstop on every copy; challenges and Endless are not validated. MIT. v0.9.2 pre-release. The lab suite drives two and three real game processes (tours plus two-process LAN, NPC, soak and chaos-proxy link tests); the Steam transport ran on Steam's in-process socket pair under one account, and no two-account Steam session has run yet. The author's own hands-on testing (not yet with friends) found it mostly works well.
