It's a sequel in the sense that the story takes place after Master of the Wind, but the gameplay and storytelling style is a lot different. References to that game's story but it's definitely not required to have played it first!
I can definitely feels the passion being put into this project I'm just like 4 hours into the game and already captivated by the story, world building and characters the qol is immaculate especially the map bit interesting choice of directions there..seems like the project is still far from completion I just hope the dev having a smoother times finishing the project moving forward bcs this looks promising man..
