I tried my best to make the foreground rain stand out without looking out of place, perhaps it needs a revisit. Thanks for playing!
It actually is fairly intuitive. I first thought it was just a mood setter, but as I started to move, rain inevitably dropped on me and I instantly understood what it meant. Furthermore, as I progressed it was clear to me that I was drying up while hopping away, and I really should aim to be soaked on rain. It's awesomely implemented as it is, and you can easily turn it into a short and sweet game!
