Marum - Steam Powered Symphony

This is a re-upload. The last time i uploaded this song, the volume was way too low. I will set the other video as unlisted.
This song was entirely made by me, with sounds from Valve's Steam. Actually, the main melody is the button pressing 'A', 'B', 'X', 'Y' when you have to input a text in big picture :)
The software used is 'Milky Tracker', which is a free chiptune software.
