A beautiful background piece.
I think it works better without any actual rain sfx.
I find that this piece didn't work so well when I was sitting and listening to it through. I mean, like a previous reviewer said, whilst it did get pretty interesting with all the layers going on, I'd have liked some more variations, maybe some more little melodies.
You know My Latest Novel/Sigur Ros? I was thinking it'd be cool if it just had maybe the various instruments kinda taking turns.
However, when you're putting it on in the bg, it does work wonderfully as a chill-out piece.
For a laid-back game, it's about ideal. My only (very slight) gripe in that role is that I'm not too keen on the way it loops.
I'm gonna use it as the bgm for my new gametype if you don't mind.
