Thanks for your message!
Looking now at it, I agree that the puzzles are a bit too hard, I'm even suprised lots of people made it to the end, I could not finish it myself now when I tried. I actually never saw Saw 2 or any other Saw movie, but I understand that some concepts could be similar.
I'm currently working on a new game that is kinda like a sequel, this time with way better puzzles, so stay tuned, I think you will love it
