Hey Petar
Great work here! I'd love to hear about your concept and harmonic language a bit more before a comment with specifics. You have a lot of great ideas with this piece, masterfully done.
Nice one. It does give me Chrono Trigger vibes. I think it's suitable as it is to go into an RPG; I might have preferred a more independent bass part in a repeated section or something, just to squeeze as much out of the ~90 seconds as you can.
