Pretty interesting game and mechanics honestly. The theme interpretation is also pretty clever. I only got to high score around 500.
On the gameplay side, I thought the game is pretty difficult. The scrolling feels really fast, leaving you with not much time to decide your actions. The hitboxes on the raining is kinda weird, or at least not communicated very well, so I had a difficult time knowing whether or not I was in the correct position to rain.
I also thought it was funny that a water particle can "die" when it fell into a body of water lol.
