Hi there! Yeah, the Linux version contains a version of the Windows EXE also, because Windows is our reference platform.
The file you're looking for is called "nw" (no extension) that's the executable for Linux.
Sorry, but I cannot run the "nw" file :( Could you help me about how to run it in my terminal? Thank you >.<
Sorry but this might require more support than I can easily give here; do you have discord? We have server:

There's a user category on there of "NALE Linux Testers"; I'm sure someone will be able to help you out.
Thanks! :)
