That sounds fun, indeed! New thing to craft, and when short with time, we can at least sleep right away.
Maybe wake up with 50% health and energy, and being able to upgrade it a few times to wake up with more?
Just an idea i just thought of.
Maybe then 50% would only be when outside, so that you have a better time sleeping over at villagers who like the farmer enough.
The Dwarf, Krobus and Sandy would like it, too. Maybe Gunther, too? :P
Should never work in Joja, might screw something up after CC... or you get kicked out several tiles away outside, so that changes won't lock you up XD
Don't use it where enemies are, though o_O
Do we have bags that we keep, or do we need new ones after each use?
A Normal Mode and Hard Mode option would be really nice with that, eh? Maybe Casual Mode to have some less restrictions?
I'd make few characters for each mode :D
But yeah, Sleeping Bags would really help, especially those with busier lives(not me, but many here have mentioned having such lives).
