I enjoyed playing this game. The story really drew me in and I was trying to piece things together through the story notes in the world. Lovely feature. The atmosphere is very dark and I enjoyed it a lot. The soundtrack is so good and I loved the variety of sound tracks provided in the different areas (outdoor, indoor, underground, etc). The art style fits the theme of the game quite well. Lovely experience.
For some feedback, I think player movement is too slow. There appears to be stamina for running but it's not visualized and it depletes way too quickly. I really wanted to explore but the slow movement felt like punishment for exploring. I understand you need to balance the player speed with enemy speed, so maybe increasing stamina recovery speed or just total stamina when the player is not aggrod by enemies is a good compromise. This is especially problematic in the underground tunnels. It was kinda a drag to explore as the player moves so slowly. Also, when using melee weapons there is no feedback on whether you hit enemies, which makes it hard to know if I'm properly aligned with the enemies. Once you get the gun, it's just steamrolling enemies from there so maybe the gun needs some balancing.
The inventory system is well implemented and I loved the tarot card art. I managed to get 100% in the game but I don't know what to do with the amulet? I thought it was to be used in the pink netherworld-like area but couldn't find a way to use it there. I do think you have some metroidvania elements (having to get the axe to access some areas, locked doors where you need to loop to the other side of the door to open it), so that's cool.
Very nice concept, keep up the great work!
