Just move the mouse cursor over the ground. The rain will fall and when it hits the ground, it will turn into a puddle and evaporate.
The inspiration for just wanting a cool project to be featured. All codes and art were made by me while I was just experimenting. The sound is just the pop sound that Scratch gives you to start off with. This is nothing special, and I made it in literally less than ten minutes. Thank you to eldershire, who helped me fix the bug so that the rain never runs out.
