Solo playing and difficulty!

Hi everyone,

I’ve watched a trailer for the game and it looks really appealing to me!

I prefer playing solo, so I was wondering if it's designed to be fully enjoyable as a single-player experience? Do the enemy count and scaling adjust accordingly for solo players?

Also, how is the difficulty compared to a Souls-like? Is it just as punishing, or is it more accessible?

Lastly, I’d love to know if there are RPG mechanics like upgrading weapons, and roughly how long the play time / average playthrough is?

Thanks in advance!
