Hmmm looks like Apple does not like games from unknown devs. You fix this by running:
sudo xattr -rds com.apple.quarantine ./The\ Reaper\'s\ Grim.app
in the directory where the .dmg file is located.
Apologies for late reply. That fixed it. Really enjoying the game. Plans for controller support? Will the world be expanded? Just started learning godot; curious how long the game took to develop?
This one took around 27ish days of development in the evenings. The game should already have controller support (just not on the UI unfortunately).
