# Teeworlds: license and credits This port is made from **Teeworlds 0.7.5** (2020), the last official release of Teeworlds (https://www.teeworlds.com/, https://github.com/teeworlds/teeworlds), originally written by Magnus Auvinen, by the Teeworlds team. * The game client and the code shared with the server (the game core, collision, maps, the network protocol and snapshots) are ported to TypeScript in `src/` (altered: a port; `README.md` lists every deviation). The game server is ported to the game server of this site, which is not distributed. * The data is the original's, unchanged: images, sounds, skins, the official maps and the font (`assets/`). ## The code: zlib license ``` Copyright (C) 2007-2020 Magnus Auvinen This software is provided 'as-is', without any express or implied warranty.

It is an adaptation of that data and licensed **CC BY-SA 3.0** like it (authors above).
