I love the low-res black-and-white graphics, really feels like a PC game from the 80s (in the best way).
This could really be something, if you flesh it out with quests and combat.
Oh and just so I don’t worry about missing something: Is 1000 years of darkness the only ending? I found the witches pre-ritual hiding in their cave, and like… can we interfere with them at that point?
