I'd advise clearing your cache and starting over for the time being! Sorry for the contrived response, I intend on adding a restart option but as it stands the VR stuff is just a big limbo of WIP content so you'll end up nowhere.
To clearify:
• The VR link we clicked took us out of the game and to a web page that was for sale; but still in the game window.
• As we were playing from the itch desktop client, and not a web browser, there was no way to return to the game, and had to close the game window.
• Despite saving the game, when we reopened the game, it was the same screen as when we first booted up the game. If there is some secret menu we need to access to load our game, we highly suggest putting the load game option under the new\start game option instead.
As for clearing the cache, how do we do that for your game in the itch desktop client?
