The Eyes of Ara (2016)

A radio signal draws you into a castle whose rooms conceal elaborate apparatus and hidden connections. Directly manipulating mechanisms is satisfying, while the former occupants' keepsakes give the building a history beyond its locks. This is fixed-position exploration, with a considerable amount of close visual searching. Some rewards are collectibles rather than the next route forward, so it suits a methodical inspector better than someone wanting a clean sequence of obvious objectives.
