I recommend a feelingz meter, you connect a heart monitor to your computer, and whenever your beats per minute reach 110% normal levels you get teleported to your safe space of choice + full heal + limb restore + weapon & armor repair to 100% + soothing images of baby ducks and chinese flute music for 5 minutes.
we need more safe spaces in this post-apocalyptic wasteland full of monsters, raiders, cannibals, killer robots, mutants, ghouls and YOU'RE MOTHER.
