When exploring caverns and laying down teathers, i end up getting lost in a maxe tryig to get out. It would be such a time saver if the teathers showed you which way the air was coming from. This could be a blue arrow at the top pointing along the line towards the next. That way when there’s a fork in the road, you can be absolutely certain which way is out.
attached is a super quick iphone rendition of it.
What if, tethers had some kind of flow inside from the source. I mean some kind of darken areas could travel inside from the source of the oxygen (from base, through branchings to the player), preventing getting lost.
