Really like this interpretation of the theme. A meteor shower feels very much like "a summer night" kind of thing to base a game around. It's such a good idea for the theme that I kind of wish there was more to hear!
Enjoying the relaxing, mysterious qualities of it all very much, the warm backing chords of the track Perseids are lovely. There's something I really, really like about the sort of repeating melodic rhythms in the background of Milky-Way. Just hits right.
Criticisms would just be that it's very short so there isn't much storytelling that can be done, or much variety, but the vibes you do go for work great.
