Item finding is of course not a puzzle (unless there's a puzzle between you and the item), but boulder pushing not a puzzle? When playing Pokémon games, I love it when I get to boulder pushing, because it's fun to figure out how to do it. Admittedly, it's almost never difficult to solve, but it's puzzling nonetheless. It takes a bit of time to solve. What I do when I make boulder puzzles is add some kind of twist, such as you need to put the boulders on the buttons to get the spikes out of the way. I saw a boulder puzzle that used buttons and spikes, and it was amazing. Done right, boulder pushing is a puzzle. . . . Oh. I just realized when typing this that you may think of something different than I do when you hear boulder pushing. Obviously when you only need to push one boulder a couple tiles to move it out of your way, that is definitely not a puzzle. When I think boulder pushing, I think of multiple boulders that are all in the way of each other, and you need to push them around in a specific way to proceed.
