Press Space to generate a random landscape. Press one of the blue triangles to set parameters, like the roughness of the terrain, or the grid size. If your input contains a weird symbol, like the ampersand (&) or the tilde (~), or is out of the requested range of the parameter you are changing, it will be rejected and you will need to try again.
I sadly have not installed seeds in this project. What results you get will be completely random. The terrain is generated in a specific way that it has a periodic boundary— which is when the edges of the grid mirror their opposite edge. Sometimes you may need to press the flag again, as some results are completely ocean, or are all land, or just a singular island in the middle of the ocean. I managed to code this by translating it from a python implementation. The python implementation: https://janert.me/blog/2022/the-diamond-square-algorithm-for-terrain-generation/diamond-square.py
