Slender with a Tinge of Grunge
I heard a clip at 0:26, a blank spot amidst the acoustics, possibly unintentional. Another issue is the abrupt cut-off at the end. If the original track still exists, then an echoing outro ought to be finessed and installed near the end to drift the listener away rather than push them into the water. I had the imagery of floating down a calm, misty lake upon a rowboat.
Only on a few occasions through the track does the sound exceed the register and things get distorted. It's a common mistake to make things too loud.
That just means you can take the original chords and riffs and compose a new version later; what's there is very good. Although the track is old, it's a smooth enough tune to be found in a game.
This definitely has a grunge aesthetic to it, as if the Seattle rock music scene influences you. It wouldn't surprise me since you've listed "Rooster" by Alice in Chains as a favorite song and you live in that city in the first place. If I recall correctly, MattZombie is from the area, along with his current band, "Judgment". Their stuff is pretty cool, too.
Anyway, keep it up, and don't be afraid to submit something old. Age doesn't kill a soundtrack, but the elements will.
