This song is pretty good, you only really need to fix a few small things! First off the general sound of the instrument at 0:22 is a bit to high pitched, I would add a little more cutoff (or whatever its called in your program). I don't know if newgrounds does seamless looping but it doesn't loop perfectly and that is key as a game sondtrack (probably newgrounds though). The melodies are good and the Instruments fit well together but the song is a bit short, even for looping vgm. You did mange to pack a lot of variety into a small song though. All in all great song! Keep up the work, looking forward to hearing more. =D
