How many tracks did you submit?
3

Explain your hypothetical game concept & how you interpreted the theme!
The tracks are for an hypothetical junkpunk videogame, in which the world has become a desert covered in ruins and metallic scrap. Like worlds like Dark-Sun the real heroes are those that change the status-quo and not those that try to keep the corrupted balance. In the game the characters aren't able to change the world in any way that matters unless they sacrifice everything, so most refuse the call to action to remain in a stable life.
The third track tries to represent the clashing thoughts about the "call"

What genre is your soundtrack?
Classical Guitar

How did you incorporate a canon into your hypothetical soundtrack?
In the first and third track we used a simple canon.
In the first track the second voice repeats the first immediately after but with a lower tone. The track is thought to be used in some sort of industrial complex/production line, so the canon is some machine that does the same thing as another one.
In the second track the second voice repeats the first with a lag of two bars resulting in a clashing melody. The track is thought to be used in a desert and the canon tries to represent the clashing thoughts of the character that maybe is thinking about the "call"

Anything else you'd like to add?
The tracks were recorded live and (for the first and third track) put together on LMMS. The recordings aren't the best, there is white noise and the there are some minor error in the execution of the pieces.
