Really digging the flow you got here, with that "shaker feel" but using a drumset. Also like the bubbly bass. Mysterious tones but not too dark. Maybe not exactly what the developer had in mind for Animal Crossing, but interesting and fitting as an ambient track. Something dark is lurking at that beach!
As a criticism, I would only say that the closing muted guitar hits at the 4th beat of the first three bars sound harsh without the snare, as if it had clipped, making the entrance to the song a bit uncomfortable, and the same again when they get looped.
