Reuploaded the macOS build without a readme to fix an issue with the game refusing to run after being extracted. If you can't run the game and you get an error saying "Unable to find game", try navigating to the directory where the game is located in Terminal and run this command: 

xattr -d com.apple.quarantine Arborescence.app

Alternatively, you can download and install the game via the itch.io app.
