Great game, it's short but packs a good punch, it has neat art, RPG battles, puzzles and a nice storytelling neatly wrapped together, the black and white stylistic choice is great and props for the ghost (I did a bit of research after playing and it seems to be a pocong?) illustrations that are really unsettling!
I played some Indonesian indie games and they always deliver with the folklore and creatures, it is so interesting learning with games; I kind of agree that the ending is kinda abrupt but I think it also somehow fits with the story? I am not sure how to explain it.
Keep up the good work!
