Intruders: Hide and Seek

Great atmospheric game! It doesn't have tracked motion controller support, but for what it sets out to be, it doesn't really need it. The Steam controller integration is flawless.
You play a little boy who goes with his family on a vacation to their secluded, large holiday home. Everything is scaled up, to make you really feel small, which works great. When night falls, you start sneaking out of your room, and scary events unfold...
I haven't progressed very far yet, but so far I can tell that the gameplay mechanics seem to revolve around stealth / hide-and-seek gameplay. In fact, before the scary nightly stuff starts, you literally play hide-and-seek with your little sister to learn the mechanics.
I can't wait to progress further through the story, to learn what my father is hiding...
Update:
I now finished it, and I must say that I really enjoyed it. The story is well-written and the great voice acting enhances it further. There are two or three well-placed jump scares in the game, but most of the suspense is driven in equal parts from the sneak-and-hide gameplay and the captivating story.
If you need a trigger warning for specific phobias, look under the spoiler:

En historia está bueno, mantiene la tensión y es interesante. Pero en jugabilidad es pésimo, lo jugué entero en teclado y es demasiado tosco. Pero bueno, se puede completar igual y la historia es lo suficientemente buena como para recomendarlo aunque tenga malos controles.

Muy buena historia.
