I absolutely adored this experience. Highlights were the first time I got told I "scared someone to death" and the smiling face of my buddy when I turned on the light for him.
Love the art and sound, it's all spot on for the classic 'horror indie' title, which makes the spin that much better.
The puzzles themselves are clever, and there's some great conveyance going on here to help you understand your objective and learn new game elements.
Delighted!
