My Feedback:
The VHS presentation is the real star. The grain, the REC overlay and the 2005 timestamp sell the found footage dread completely, while the colored cube puzzles and the candle ritual keep you moving with purpose.
SPOILER!!
I did experience a strange bug, if you jump over the chair/dresser before the bed scene starts, there is no way to get back into the room as the other door locks and can only be opened from the inside.
