Space to run the function E to input seed More Octaves makes the process take slightly longer but increases the amount of layers, making the noise more detailed. Low Octaves create a smooth but blurry noise while High Octaves add smaller and smaller details. Zoom simply zooms in on the bottom left of the noise. Each level increased doubles the zoom. I built this right after making my value noise algorithm. I'll probably be using this for my 2D Minecraft project i'm working on. Have fun!
