Playing this and having great fun, superb atmosphere!
Since it is Godot, can I pester the devs for a Linux build?
You can! We're not sure if it'll actually run on Linux because I just did the export--but as I have your email I took the liberty of sending the link to you; if it works, then we're golden...at least for some values of "Linux," hehe.
Update: The Linux version that's public is newer and (hopefully) will run for you since someone on the MVM discord tested with a Chromebook.
