You have so many great ideas going on and a really cool idea for gameplay! Because you have so much music, I wanted to at least share my one favorite thing from each track:
Wishing: The echo of the viola after the marimba is a really cool effect! It gives me ideas for things I want to do in my music going forward.
Starlight Resonance: The way you layered the main melody gives it that chorus effect that makes songs seem to get stuck in your head. This works really well as a main theme for your game and can lend itself to great motif development.
The Starbeam Palace: Your blend of instruments and harmonies captures the interesting combination of a medieval/rural village existing in space- what a challenging combination to create!
Lululand: My favorite part is the brass synth transition into the synth and drum section at about 1 minute into the song! Definitely good training music.
Windy Wisps: The use of long attack time makes me think of the wisps fading in and out. I think this is good use of musical imagery.
Drylands: I am a big fan of the use of traditional Middle Eastern and Indian instrumentation to create desert-sounding tracks. This is my favorite of all your tracks!
The Flow: The rhythmic element of the mallet instruments and the beats on 1, 2+, and 4 give this galaxy a tropical vibe which works very well for making me imagine a water-world area. Overall these are some awesome tracks and would love to hear more if you plan to finish it! Thank you for sharing!
