If you loved Ousama Game, try P.O.V. A Cursed Film
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Norio Tsuruta, and they both carry the dread, paranoid mood tags, and they sit in Horror / Thriller territory. If that's the register that drew you to Ousama Game, the second film will land in a comparable space — through a different lens.

What P.O.V. A Cursed Film is
Hazy corridor after midnight. A phone screen glows. The footage jumps. Urban legend slithers off the tape. Two hosts follow the cursed clip to its source, a school where a psychic orders a ritual that should not exist. A J-horror puzzle box.
