If you're in a cavern layers one does anyone have any tips on how to either go back up to the cave entrance you came from or down to cavern layer two?
For some reason there isn't shit here but some giant cave spider webs (my adventurer was even completely undisturbed for 8 hours of sleeping), so it's pretty boring here.
Up - use the Q menu to find out roughly where you are.
If you have an exported map of your world (a pic can create at the end of worldgen or in legends mode), and you had "show caves" on in the worldgen, then use it to figure out where the closest cave is. (The only ones showing on that map will be ones that went down to the caverns, I think)
You can use these two resources to figure out where the closest cave access
should be, and then get there.
Bonus tip: if you do get deeper, don't go anywhere
near the gas bag things. Floaties. Them. Don't touch 'em. Early last year Toady had H1N1. If you get anywhere near the floaties, your adventurer will know Toady Of Last Year's pain.
