I'm not sure what can I say that others have said as feedback so I'll just say my experience.
I started the game and after picking up different items I just guessed they were all props and just did combat only, at first I was cheesing with a door getting the enemies stuck and eventually I started doing more proper combat as I felt more comfortable with attack timers and enemy behavior. I'm not a souls player so I'm not sure if I should comment, it felt a bit clunky but maybe that's intended since the enemies are clunky too.
After a bit all enemies were dead but one that didnt have an hp bar who didnt attack me, I thought it was some friendly or bugged npc. Eventually I opened a door that lead to nowhere and fell off the world, by this point I took a guess that the game didnt have much else to offer, I hope this wans't incorrect.
