This is a rewrite of the original CodeSpell game.
You can download the binary releases from: https://github.com/codespellv3/cs_mp/releases
If you want to modify the source, the Unity version I used for development is 2018.3.14f1. Newer version might be incompatible.
Have a look at the wiki for additional information on how to use this repo.
You can find more information on the old versions here.
