This is good but could be better. I'd like to see the following enhancements:
1) When it randomizes between storm types, it fades out, pauses and fades back in. This is kind of disruptive. It would be nice if it were a quick cross-fade.
2) The mood music backing tracks are too short, repetitive and have similar fade issues as the storms.
3) There's an overall volume and rain volume, but no music volume. I'd like to leave the rain loud but turn down the music. It would also be nice to have a separate thunder volume, if possible.
I would send my feedback directly to the developer, but the only channel for that is Facebook and I don't do Facebook. It'll be just about perfect if they make these changes and I'll gladly update my review. I hope they see it here!
