So I just solved a puzzle, but I'm almost sure I didn't do it the way the developer intended. It's in that room that you can access by going through the eye door located behind the Leap of Faith ("Walk?") section. I think it's called "A Game of Leapfrog" or something like that. Anyway, there are two cubes, and you have to get it so that a cube is sitting in between the two intersecting lasers right in the middle. What I did was I went out of the room, across the Leap of Faith, to that part where there are a bunch of cubes lining one of the hurdles. I took those cubes back to the Leapfrog room and piled them up until they reached where I needed them to go. I feel like there's definitely a more elegant way to do it than that.

stone, that was the easier way to do it lol, i did that too. i think the developers for the most part encourage figuring out the puzzles by whatever means you can think of. some puzzles have one solution, some have multiple
I've noticed little details that are very well thought out that prevent or allow blocks to enter certain areas. I'd say the dev gave this game a RIDICULOUS amount of thought. If you were able to get blocks into an area to solve a puzzle, chances are it was intentional.
Remember the note you get just after solving that puzzle? I forget exactly what it said, but it was something along the lines of it not being wrong to get extra help. It was essentially saying that using those blocks was not only perfectly fine, but they expected you to do it. =)
