Is there any chance this game will ever get a version for macOS that is at least X86_64 (so it can run on new macOS versions and even on Apple silicon through Rosetta2) or preferably a "Universal Binary" So it could run on both Intel Mac's AND Apple silicon.
The current version is 32-bit and this is not supported by the latest 2 versions of macOS.
I don't know what environment and game engine is used to for this game but I would assume most modern development environments would have support for this (at least the X86_64, and probably ARM64 in the near future)
