This feels like it could've come straight out of an actual retro game. The loops are really well done too. Nothing ever started to grate on me or feel repetitive, and I could easily imagine these playing in the background for a long time without getting tired of them.
I especially liked the panning. Having different instruments bouncing between the left and right while the main voice stayed centered made everything feel way fuller than you'd expect from chiptune. There's a lot of substance here despite the limited sound palette, and everything has its own space.
Really well composed and really fun to listen to. This just feels like proper game music.
