Ok, so what to you differentiates, in general, a "real" pixel from a "simulated" pixel? It's not clear. Is this a term of art that games industry insiders know? I understand what weather forecasters mean when they talk about "hurricanes" vs. "simulated hurricanes" . So how does that apply to pixels? I apologize if I came across as dismissive of the headline, but there is a genuine comprehension gap here. OK, you understand it just fine, but that reply doesn't help me close the gap.

  In regular 2D games most pixels are simply drawn, based on a sprite or texture. Think Super Mario, each block of ground is a sprite, each coin box is a sprite. The sprites might be drawn based on more or less involved simulation, think the mushrooms that move and change direction when they hit an obstacle. But the pixels making up the mushroom is just drawn based on the mushrooms location, same as always. In Noita you can think of each pixel on screen as being a 1x1 sprite. Each one simulated.

      Well in say Super Mario, most of the sprites aren't simulated at all. They're sitting at fixed locations in the world. The viewpoint changes, but the sprites (tiles) stay where they are. In this respect Noita is like Minecraft, in that each pixel (block) can change. However in Minecraft the state of each block in the world changes while its position is fixed. In Noita each 1x1 sprite (pixel) can move around on its own.

        > in say Super Mario, most of the sprites aren't simulated at all That's not a statement that I find a lot of meaning in. The sprites are not imitation sprites? The sprites are not fake? ( https://www.merriam-webster.com/dictionary/simulated https://www.merriam-webster.com/dictionary/simulated ) Do you use a different definition? What words would you use as synonyms of "simulated" here? "Animated" ? "Interactive" ? "run through the physics engine" ? it does seem to be a term of art here.

        I think the key behind simulation is that it's dynamic. The way the coin box bounces up and down in Super Mario doesn't change in a dynamic way. Once triggered it goes through a predetermined motion. This is unlike say the turtle shells which bounce around depending on what it hits. Its motion is dynamic and dictated by what the player did and the environment it's in. The distinction between animation and simulation can be a bit fuzzy, but for me an animation is typically a predetermined motion while simulation is dynamic and reactive. However, especially in modern games, animation is blended with simulation to increase realism making this distinction less clear, see for example https://youtu.be/yTniZCOCY7o https://youtu.be/yTniZCOCY7o So coming back to Noita, think of every 1x1 sprite in the game world as a Super Mario turtle. They can change state and motion in a dynamic and reactive way.
