First off, awesome work and congrats on your first Jam submission! This OST is really good work and I find each track works very well together. You have an awesome knack for story telling, and I enjoyed listening to each of these tracks.
Night Sky sets the atmosphere of the game, i love the gentle synth that comes in and continues to build until the drums towards the end. It really helps convey the message of time passing and the star growing and changing to be more vibrant!
Meteor shower/falling stars might be one of my favorites. The wooshing/waves? sound that you use in the beginning adds a really cool element to this one.
Her wish is actually a really awesome part when combined with your story, and the beeping at the end is awesome. Nice working incorporating your story telling into the music, I think that can be a difficult task to achieve with game audio. But this is a perfect example of good story telling through audio.
Blackhole the Bass synth? reverb i feel fits the inside of a blackhole, and the cymbals? That are wooshing past are a nice touch, again a really powerful show of storytelling through music.
Rebirth is a really cool wrap up to this story of a stars life/journey. What is the buzzing sound/instrument that you used that starts right around 1.23? I like it! And when it fades of at the end and pans back and forth is really cool,
The Full length version of Meteor shower is awesome as well! I guess I lied saying meteor shower is my favorite, I like the extended version! The extra part with the guitar? at 1.42 is really chill, but then the change up at 2.16 when the drums come on, I love this part with the synth and was grooving along with it :D
Thank you for submitting and sharing this one, i loved it and would love to see a game like this made! Sorry for so many question marks and mistakes identifying instruments ha I'm not so great at that yet:p
