Wow, this is an incredible game you've managed to create during only 9 days. The movement through the rain drops work very well, and it just makes fun to try to catch the next one. I understand the difficulty issues of the other players, but for me the challenge was part of the fun because I realized pretty soon that it would work out after a bit of practise.
In contrast to the suggested solution, I felt like flying against the wind was more effective for me, since it was easier to hit the next rain drop.
Last but not least, the visuals and audio fit very well to the game, too. Good job on this entry!
