This was a blast to play. I didn't actually expect to have so much fun. I think the music really helps you get into it, so you've done a super job a the 'Ambiance' creation there and obviously the music. As some others said I wasn't 100% sure what the drops were doing or what the benefits were, but it was clear that they were having a cumulative effect on the gameplay, firing faster, walking faster etc, so even though I dont know entirely what was happening, you clearly had great mechanics built into the game as well. Really cool game, really great job - well done. You should keep working on and developing this game. You've got the makings of a good bullet-hell game here.
