This is Survival Horror Story: Catequesis, an 8-bit horror game with religious undertones. It's... pretty scary.
Above we have the newest trailer for SHS, which, as you might recall, stars Daniel, a boy trying to rescue his girlfriend. As you can see, the game is aiming for a good, dark atmosphere rather than graphical fidelity. I'd say they nailed it. Gameplay is, according to the developers, reminiscent of the first Zelda, with an ambience similar to Silent Hill's or Resident Evil's.
SHS: Catequesis hits the PC sometimes next year — a delay compared to its previously announced release date of Q3 2013. A damn shame, really, but here's hoping they'll finish up soon. You can keep an eye on the game here if you're interested.
