The gameplay is really fun and very creative, although I found as I kept playing, the red strings would just overlap and not disappear which did get in the way a little bit, but I found it funny and it's so, so minor it doesn't matter.
Also, I HAVE to mention the immense detail in all the textures! Seriously, I spent more time looking at everything than actually solving. The details like being able to barely see "North C. Case" labelled on the door backwards, and seeing the name further on the framed degrees. Along with the personality given with looking at the objects, and the really neat fake game posters. The music is really atmospheric when paired with the lighting too.
Overall, this is awesome and unbelievably polished! Great Work! :)
