Not much too it, extremely short, but what is there is effectively creepy and unsettling. The visual style, coupled with the camera being both the progression tool and the only source of light, works very well. There is no ambient sound or loud, distracting background music, only the sound of the player character's footsteps and an ever present ominous tone. The story is told, or rather, heavily implied, by the various items found in the apartment rather than being spelled out directly and explained in full, leaving much up to the speculation/interpretation/imagination of the player. Again, very short, could have been so much more if fleshed out and made longer, but what's there does what it was meant to do and does it well.
