Stranga Games delivers on with Yokai-themed adventure games, with light leanings on horror and easy-going humor to even up the mood balance. My Big Sister is one major entry by Stranga's standards. I played it after its prequel "Ashina: The Red Witch" story-wise, and the connection of the characters in common helped make sense of the story where answers to questions would come further along the progression. It's story-focused with light puzzle elements that doesn't veer off much from object-finding and basic exploration.

The story of two sisters, including one turned to Yokai (ghost in Japanese), is a less common theme and involves some evolving plot twist along with the story. While the story bears some merit, the game has some jank in the mechanics and might take away some bit of enjoyment. But if you don't mind that and want some light Yokai semi-horror to boot for an adventure game, My Big Sister is a decent entry to go by. Personally, I'd recommend you check out its prequel Ashina, which came out after this.
