How do i win fights even?
Howdy!
The game is a work in progress, so currently you're only able to explore. Main story stuff does come up, but there's no definitive "Victory" state yet.
As for the battles, I presume you mean at 'The Scar'. Every fight had a gimmick you can exploit, and you can buy items to make them easier. Be warnes that brute-forcing combat tends to result in you taking way more damage than is sustainable.
