in my view this game doesn't really need or benefit from the AI narrative but the gameplay itself is awesome. I tend to think I have really bad spatial awareness but I was surprised by how easy (but still challenging enough) most of it was for me. the hardest part is always figuring out what order to draw the lines in.
one thing that confused me slightly was the hints timer. when I used up all 3 available hints it said '20 mins till next hint' but I expected it to count down so if I clicked again on it 5 minutes later it would say 15 mins till next hint, etc....not sure if i'm misunderstanding something.
