Hey there,
Sorry for the issues, the GOG installer for 1.2.0.0130_Bundle is now uploading and will be ready shortly. I'll post an update once it's done! For version reference, 1.2 is the Major and Minor, and 0130 means released 30/01. This installer also includes the Director's Cut of the original game that was released yesterday too.
You'll be able to download the new installer through normal means on itch.io.
