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?
