What a fresh submission! *-*
I loved how you made the rain the main resource of the game: it's always available, but has to be redirected to face the (cuuuuute) little enemies. That's a very intersting and original mechanics, and I would love to see more based on this.
The animations and the graphics were nice, even if the wind sprite confused me a bit: it was hard to understand the direction it was pointing. The SFX, on the other hand, really helped to create a beautiful atmosphere!
Great game, good job :D
