Liked: The puzzles tickle the problem solving part of the brain. I love it.
Could improve: Obviously you could add more puzzles to this. Another thing I think this could benefit from is just straight up telling the player that trust no one. I some how lucked through all the levels until the last one which I couldn't figure out with the logic I had created so I went back and I realized all of them are lying and not just some of them XD.
Additional Comments: The puzzles are fun to figure out especially the last one. I got excited when I finally got it right and was expecting something harder but unfortunately it never came. This is a great game regardless, Good work!
