I'd download the demo, but I'm on a Macbook so the browser version is more convenient. Thankfully, I was able to pick up from my last campfire just fine after each crash.
Re: the daughter character, I did find the crafting and management aspects of the game to be interesting. I found myself able to hang back and let the Wife handle a lot of smaller challenges alone with her bow, which is great, but I'm curious what other mechanics you've played around with (like, did you ever consider having the family respawn at the last campfire after dying, rather than in the same spot? was that too onerous?)
