A great composition! The themes both the melodic and rhythmical aspects are very clear, they are not overly complex and simple enough to be catchy and easily remembered.
One thing about this challenge for me is seeing what piano VST everyone used and how it works with their composition. Also, by being limited to only the piano one has to be more mindful of how "real" the playing sounds and some types of styles/compositions work without needing to sound real. For your piece, I think the composition is very very good. If you were to reorchestrate this it would still sound amazing. But, since it's solo piano and for me this piece works great as a solo piano piece I wonder how it would sound programmed a bit differently or played in real life. For me, there is a bit too much pedal and there are some parts that would sound super good with more staccato. The melody is super beautiful but I think some parts to be a bit clearer. Maybe it's the specific VST used, a bit too much pedal, or not having the main lines a bit more velocity would give it a bit more clarity. Video game music in general kinda "gets away" with a lot more since the visuals are not from real life but since this is a music jam only I tend to judge all pieces based on the music alone (and/or if the description gives something extra insight). Not sure if I managed to get my point across....
Lastly, I think this is really great and the composition in itself is very strong. It has a good balance of simplicity and more complex harmony/textures/moment. My only wish is that the programming sounded more real which would show how well written it really is.
Very good piece and I'll for sure listen to it more!
