Not going to lie, I was 100% expecting this to become a horror game with the darkness and the lighting and was very disappointed to find out it was not that lol.
Decent execution, but constantly having to find your split personality between stages did not really tell the story for me. Exit areas also are really hard to distinguish and need a visual flag or some other visible element to let players know where to go. Something that could literally be invisible until united with your other half.
