Hi! You've packaged your game wrongly for release here. The game won't run in the engine because the files you provided are the files you used for your project development, not release. The bundled luastg file can only be run by the wxLua editor of LuaSTG for later code generation, which is unoptimal. It would be more convenient if you just packed your whole "game" folder and uploaded it here instead. If you're unsure about THlib's licensing issues, just pack the actual files inside your "mod" folder instead and upload them instead. You can message me if you have any questions and I'll be happy to help!
