v2.2.0

Opening on macOS

No paid Apple Developer account yet, so the macOS build is ad-hoc signed but not
notarized. On first launch Gatekeeper may say "XSpaceWar-AI is damaged and can't
be opened." It is not damaged — macOS just quarantines un-notarized downloads.
Clear the quarantine flag in Terminal and it opens normally:

xattr -dr com.apple.quarantine /path/to/XSpaceWar-AI.app

Right-click → Open (and System Settings → Open Anyway) do not clear the
"damaged" warning — only the command above does.
