Download the game
Made with Godot 4
To play outside the browser, offline too. Packages built from v14.
First launch
- Windows — unzip it and open the .exe file. The game is not signed: if Windows shows “Windows protected your PC”, choose “More info”, then “Run anyway”.
- macOS — unzip it and open the app. It is not signed by Apple, so the first time macOS blocks it: go to System Settings → Privacy & Security and choose “Open Anyway”. If it says the app is damaged instead, type this command in Terminal, followed by the path to the app:
xattr -dr com.apple.quarantine - Linux — unzip it and run the .x86_64 file. If it does not start, make it executable (chmod +x).
- Android — open the .apk file on your phone. Android asks you to allow installing apps from this source: allow the browser once, then tap “Install”. It needs a 64-bit (arm64) phone.
Milestones done: 10 of 10.
