As most people know, I am a videogame pioneer. I got really, really tired of things like "push the block" puzzles, so I decided to develop new mechanics for videogame interaction, such as sand. Yes, sand! Why bother with "push the block" cliche puzzles when you have something like sand at your disposal? To give an example on how this works, you can get some empty sandbags, and fill them up with sand. Then you can push them around and stack them and make things like stairs.
