Particle Density Option 🌧️🍃 (Patreon)

Added a useful option to set the Particle density~

Low will only render rain, while High will also render leaves in the wind and other special effects (consider wind and rain are not tied to each other, there can be rainy days without wind or windy days without rain)!

There's also a None option, to make the game much lighter to run when sun's not out!
