This track was made by Harry101UK, I am just uploading it to Soundcloud from YouTube. 

Portal 2 - Portal Stories- Mel - Interfacing

One of my favorite tracks from the Oneshot OST. Took me a few weeks to write. Theme for the Refuge (city area).

On Little Cat Feet

Not made by me.
It is the song used for the trailer for Portal Stories mel.
Awesome game. Really good song too.
This is the trailer one.
There is another one with the same name but is used for a level in the game. (different sounds)

Troubled Water [Trailer Theme] Portal Stories Mel

A boss theme I originally made for the end scene in Portal Stories: Mel, but it was changed later in development.

This is my original vision of the track, and my personal favourite. Now remastered a bit! ;)
