I still have problems with exporting Godot projects for Mac even in most recent Godot. There is no way to sign with ad hoc signature and without it MacOS does not allow to launch the exported build. You can just clone https://github.com/aleksandrbazhin/TilePIpe and run it with Godot, it is not that much harder.
As for me working on it - I actually was working on a total overhaul and release of TilPipe2, which will be more useful. The release is pretty close, but the exporter is not ready + the docs are still to be created.
Thanks for the donation and the kind words.
If you can somehow advise me on the Mac issue, I will update the build. I am not a Mac user, only have a Linux PC now.
