0. I have also tried passing the embedded "path" TextAdventure.Assets.unifont-15.0.06.otf straight to the Font constructor (both relative path & appended to the absolute path of the assembly). I have also put the .otf file in a Unity Asset Bundle and used AssetBundle.LoadFromStream(fontStream).LoadAsset<Font>("assets/unifont-15.0.06.otf") to try and grab the file.
