Thanks for playing! I also just started looking into procedural tilemaps and it was a good fit with the theme so I went for it. The map is generated with perlin noise and a threshold to detect "land areas", then I try to find which tile should be displayed in each cell by looking at the adjacent tiles, flags and bitwise ops make this part much easier to write. I also double the original matrix so that the smallest unit of land is a 2x2 square, so I don't have to deal with too many tile types (no single tile completely surrounded by water or tiles, no "bridges", etc)
