This is a mod of CelLua Machine, originally made by KyYay. This repository contains a launcher as well as files required by the launcher.
Just run the launcher. Make sure to run it as administrator or it won't be able to write the files properly. To make a shortcut for this, right-click on it and select Properties, then Compatibility, then check the box labeled "Always run as administrator".
Unfortunately, the launcher won't work. Make sure to download the appropriate discord-rpc file and place it next to your LOVE2D executable. Then download the latest version manually and run that.
