This idea has come to me for a long time.
The weather in the game stay the same of all time. That is not quiet interesting at all. I really thing that if you can add rainy, sunny, stormy in game will make Grounded more challenge. Because we are tiny, every rain drop will very dangerous if we get hit by 1 water drop. And season, we can simple seprate into 2 season: Flood season and Dry season. With flood season, a lot of map will sink in water, that make player have to use water item more often. And Dry season will make something show out, that relic only can access in Dry season. Weather and Season will really make Grounded funnier and more challenge.
