Yeah it's just about surviving for as long as possible at this point, sadly I didn't get to add a lot of the features I had planned for like combat and more complex water management stuff. Watering a grass adjacent to a desert will spread the grass to the desert, which can spawn new resources but at current the resources don't really have a limit so there's not really a need to look for more once you've found the basic ones. I'm planning to keep working on it though!
