I'm not sure if this issue has already been reported (I did try to search for it), but sometimes I'm unable to save the game. When I press ESC, the menu doesn't open. However, the ESC key works normally when I use it to store or remove items, for example.
This significantly impacts the gameplay experience, as it's important to be able to save at various points before progressing, collecting items, or taking any other actions.
If there's already a bugfix for this issue, could it please be posted on the main page?
Note: I started a new game.
