Every area, object, enemy, boss and NPC (by the way, you missed 3 of them) have a story. It's like a souls-borne game, you have your story and a huge lore to explore :)
We are not english native speakers, so we decided to release a gameplay-only demo (it's not easy to translate complex text).
Anyway, thank you for playing and congrats, your video is amazing (but you missed a lot of things :D).
