From my perspective when I played, I didn't find many survival elements. It's just the hunger and that's about it. The crafting doesn't behave like normal survival games nor does the gathering of resources. Hunger just seems un-orthogonal to the rest of the game.
I did find some other items, I made it to what I think is the end of the demo, with the boss fight. Although I couldn't beat him. Each time I died I just used the exact same combination of items which is the EXP loss, burn resistance, and super dodge duration items.
And finally I did play on Wine with Linux but I still have the save data. And yeah you just can't load the save, it keeps giving the same error.

I hope that's a good way of sharing it.
