So I really really love the second and third puzzles in this, but I found the first puzzle so frustrating that I almost gave up on it before I got to see them. It was really smart to record a guide for the game so that didn't happen.
First Puzzle. I really love the idea of perspective puzzles like these, but I wish there was a way for me to input the answer on my own. I found a few numbers in the first puzzle and some glowed and some didn't, and I had no idea what I was supposed to do with them. I ended up looking at the walkthrough to figure out how to position the camera to tell the game that I found a number.
