I have some points for improvement:
- I didn't really grasp what to do with the potions I get from chests, they don't appear in my hotbar.
- When I press space inside the graveyard, the textbox appears and never goes away
- The rain effect is a bit much, I would tone it down
The premise of the game sounds nice, but I was missing some sort of gameplay introduction inside the game. Also, I think you are underselling your theme interpretation inside your GDD a bit. In the introduction you make quite clear how you incorporated the ideas of Shadows and Alchemy.
