Good atmosphere, very Dark Souls 1/Demons Souls-esque, down to the sound effects. The armor with the armet/shawl combo vaguely reminds me of the Alba set.
I defeated the doppelganger at the church. He had it coming.
I think what you need the most in terms of gameplay is a lock on feature. You can totally play the game without it but the sword has a 3 hit combo and I think you need a lock on in order to connect that last hit.
Keep up the good work.
