I thought to myself, "where do I remember the name 'Ray Nexus' from?" And then, when I scrolled through your works, I figured: "It must be from Songtember!" If that is so, it has been a while; good to see you hear :)
I can tell from your artist message that you had little time to make this, which explains the the repetitiveness and simplicity of the songs. Murnai has a great beat to it and a cool melody, but I just wished for some more variations - whether that be new instruments, new melodies, or new chord progressions. The sustained note in the bass gets stale after a while, and you could switch it up by going for alternative baselines. Nest feels really fitting for a mystical dragon environment with the echoing notes and choir. You've got a solid start, but here too, I would love to see more variation. I notice the common pattern of incrementally adding instrumentation, but sadly that often leads to the same chords and melodies playing for the entire duration. A good example of a song that incrementally adds instrumentation but also switches it up so now and then is Deltarune's 'Scarlet Forest'.
Overall, nice entry, and good to see you here again :D
