I personally loved this demo and would love to see more of it. I was a big fan of the extraction style gameplay. Very solid foundation for the combat system too, plenty of room to add more weapons and systems with what you have in place.
Now just a small suggestion which would address the thing I was most frustrated with.
I definitely think the ability to craft without having to remove items from storage would be biggest QOL update you could make at the moment.
But yeah otherwise 10 outta 10 would absolutely love to see more of this.
