This game is amazing! The only frustrating bit for me was for the life of me don't understand what to do with the mirror (solved the rest)
Hint: Look at it veerrrryyyy closely. The solution is more obvious than whatever you're thinking
EDIT: got it
is it correct that it doesn't end? They all highlight and nothing happens
Keep playing! Theres a final puzzle, make sure you talk to the phone guy regularly and keep an eye out for anything weird!
