With my best guess, I would call it chill-classical... but I'm really not sure. I find that some of my own stuff falls into that awkward space between several musical genres, but I think that's what makes them unique!
It is a little bit repetitive, so I would almost say it could fit as a loop in a game. All it needs is just one more section that carried a different variation on the melody, rhythm, or instrumentation. It needs a section that sounds like a turn of events, or like something has definitely changed. With music, we are telling story, sometimes without words. We try convey imagery and emotion through audio alone. In this instance, there isn't much that strays from where we started, so it doesn't feel like the listener was taken anywhere. Typically, we want to start somewhere, go somewhere else, and then either return home to where we started, or leave the listener in a new place entirely. Therefore, I think this tune could benefit from a section that feels drastically different from the rest, while maintaining just enough similarity that it feels like it belongs in the same song.
I do like the variations on the melody as the song progresses; they slowly evolve into something a little darker and more solemn. This prepares the listener for that turn of events that I mentioned.
The strings in the background combined with the drums, give it a spacious, chill vibe. (somewhat reminds me of Metroid) However, the piano clashes with this vibe as it drives the melody a little too often. If you were to have the piano play a little less often so that its more like a spice that's sprinkled on, it would add to that sense of ambiance. This will make it feel like there is more space, like things are slightly more barren. In contrast, if you wanted to lean into the melody, I would suggest picking a point in the song, upping the complexity of the underlying chords, switch up the melody a bit, and add to the busyness of the drums to really intensify things for that one section.
The mix is good, but a bit quiet. I can hear all the instruments playing, but overall the volume level is really low. There's no need to blast it out of the speakers, but definitely turn up the overall volume of the mix so it has a similar level to other similar tracks.
Good job, though! Keep making more music and keep experimenting and learning! I want to hear what you come up with next! :)
