I downloaded the new version, wiped out my last savegame, and start a new one.
First surprise, I know deserts are hot but... The stun damage is not a little exaggerated? The castaway "dress" give a 50% stun damage reduction in hot climate, even with this, my gals can´t stay more than a turn in the wild without passing away. It appears that the damage is exponential, and relative to absolute health. THe first turn, about a quarter of health, the second, pass away. It is interesting and forcing you to have your canteen, but, I ask again, It is not a little exaggerated? Maybe I´m just a whimp P.
