Fun demo! You seem to know about the controller issues already so I'll skip that.
My main critique is the game is very easy. I don't think I died once and I beat the end boss practically by accident, two levels in the gun stat was enough to obliterate him with the pistol. The difficulty plays nicely with how easy the campfires are to overlook. I kept thinking they were decoration, and I wasn't punished for skipping them.
That being said, I can't wait to see more of this game. The core soulsborne themes and mechanics translate very nicely to a wild west setting. The world building is already solid, which is a great indicator. I want to call out deputy summoning hanged men as one of my favorite moments. The fight may have been easy, but that was cool as hell.
Keep up the good work!
