I'm not really fond of exploring the caves, but it seems like that's where all the story gets resolved. I don't care about spoilers so, do I need to spend all my time spelunking to progress here? Scavenging for batteries is kind of a pain in the butt, the improved stick as torch doesn't work well. What's the solution? I'm feeling like giving up on all this cave BS.

Is it okay to use a leaf trap or hairspray with a lighter? And how do I light up the cave without it attacking me?
