itch.io

Thanks, that helps a lot. It's most likely a corrupted cached copy in your browser rather than a problem with the build itself. Unity caches the game files locally so it loads faster next time, and if the first download got interrupted, it'll keep loading the broken copy every time after that, which is why refreshing doesn't help.

The quickest way to check is to open the game page in an InPrivate window with Ctrl+Shift+N and try it there, since that ignores the cached copy. If it works in InPrivate/incognito, then that's confirmed and you can fix your normal window by clearing the stored data for itch. In Edge that's under Settings, then Cookies and site permissions, then Manage and delete cookies and site data, then See all cookies and site data. Search for itch in there, delete it, and reload the page.

If neither of those works, feel free to dm me on Discord (tiny.hawk, im in the Synty Discord)  and we can figure it out there. Sorry for the trouble, and thanks for giving it a shot
