Thanks for playing!
Did you actually game over from that, or did you just see it in the "conditions"? I ask because it's supposed to be rigged to be impossible (so the player has a sense of urgency even though there's no actual danger) so if the villager was able to die for you that's a bug and I can look into it.
Permadeath is supposed to be a thing in this game but there's no way to stop people from alt+f4ing whenever a character dies so I could add a "quit to menu" or "restart chapter" to at least move the process along a little quicker.
Checking attack ranges is a bit obtuse right now. You can see the range of the currently equipped weapon by "inspecting" on it in any of the menus that show the inventory, along with other stats, like might (damage) and weight.

Oh boy, you'll like what happens in the next chapter then ;)
