A simple terrain scanner. NOT a terrain generator. It scans an image to get the terrain. Press Space to re-scan the image. This way, you can see other maps. This can work on any image, but the value for sea level (threshold between water and land) needs to be tuned to that of the image also, currently terrain type is also defined by an image, so that should also be considered, but a simple image editing program can be used to generate the image.
Not meant to be fast, instead just a test. Turbowarp will LOOK like it crashed, but you just have to wait. https://turbowarp.org/1227897110 Website I used to make the images: https://kleki.com/ instructions for how to make images with THIS website in project (image sprite)
