The Excavation of Hob's Barrow is the eighth and final game in April's Humble Choice Bundle. It's a 2.5D pixel-art point-and-click horror adventure set in Victorian England.
You play as Thomasina Bateman, a grave-robber... sorry, "barrow-digger", who's been asked to come to a small village in rural England to excavate a barrow (a large, round, ancient grave).
When she arrives by train in the village of Bewley, the man she's there to meet is nowhere to be found, and the locals claim to know nothing of the site known as "Hob's Barrow", with the mystery unfolding from there.
In this case, the narrative does lift the game above my resistance to pixel-art games, but it's definitely a game I'd need to be in the mood for.
