This sounds great! I'm not 100% sure how many tracks are supposed to be in this, but I've got some technical notes (since subjective notes often are up to preference)!
Make sure the music loops seamlessly (I assume that it's supposed to loop). I might be wrong guessing on this, but it might be a file issue as well if the music files are mp3. (in case this helps other ppl) Mp3 files often have a tiny gap at the start of the file, which is why wav is more commonly used. Using audio middleware and such would alleviate some of those issues as well! Composition wise, some more variation in the chord progression and motifs would have been nice to see! Overall, the music accomplishes its purpose throughout the gameplay and elevates the vibes.
