Nice game
The concept somewhat reminds me of Fishy, The controls can be a bit strange since it takes a second for the drop to catch up with the mouse, but I think this adds a nice challenge to the game. There are two things that kind of bug me though, for one, they'd all fal at the same rate regardless of size, and for two raindrops, contrary to popular depiction are not tear drop shaped, but rather perfectly spherical, which you can see in slow motion film capture of rain. The game is still fun though, and you definitely chose good music and sound effects for it.
