It's worth exploring your options
Sometimes it really seems like you’ve found yourself in an impossible situation. While those certainly can happen, games regularly teach us that it’s worth doing a quick recap of everything up to that point to see if you missed something. Point-and-click players will know the strategy of “click on everything” all too well, but it can certainly apply in real life. Don’t discount things just because they seemed unimportant earlier. Hunt around for new pathways and perspectives. You never know, you might find that the answer was there all along.
