Thank you very much!
Wayfarer is a browser-only game while it is in development, which means it can't be downloaded. Could you explain what kind of issues you are experiencing with compatibility between your browser and the game? And also which browser you are using and what kind of device you are playing on?
If your browser is refusing to run the game after you click "Run Interactive Novel", check your adblockers and other extensions. If you run something like UBlock Origin, you will need to whitelist the game page for it to run properly. And there's a post here with some guidance on troubleshooting common game launch errors here!
If you do want to play offline, the game is available on the itch.io app (desktop only). This is not recommended as you may run into save, UI and loading issues as the app doesn't play nice with HTML games.
