Listen to the soundtracks:

Disclaimer: Please do NOT use any of the soundtracks submitted to this jam without permission from the artist, they are not free to use unless otherwise stated.

Compose an original soundtrack of any style for an imaginary game!

But hold on, how am I supposed to know what to compose if I don't know anything about the game I'm composing for?

Well, that's the twist of the jam, you don't. You need to imagine that part by your own.


a journey to remember.

Choose either the theme "a journey to remember." or the picture theme, or both. Art by @Pixel_Pit

Note: The themes here are more like an inspiration, and strictly speaking there are no specific musical "theme" for you to follow and that you can compose in any genre you want, so the submissions can be as diverse as possible.


Compose at least 3 minutes worth of soundtrack. 

You can compose as many tracks you want, providing that all of them is practically made for the same game, meaning each tracks needs to interconnect and not be far-off from each other. To achieve this, using leitmotifs is strongly recommended.

It can be in any genre you want: 8-bit, orchestration, electronic, ambient, etc. It can even have vocals/lyrics! It can also be loopable, have a proper ending, connect to the next track, or just a simple fade-out.

You must submit the original recording in either mp3 or flac on, with a screen recording or screenshot(s) or pdf of your DAW, score, or tracker. (This is to prove that you are the original creator)

Additionally, you can also provide a description of what kind of game the soundtrack you composed is like, what does each track represent in the game, etc. You can also provide a link to the tracks on streaming services such as Soundcloud or Bandcamp as well.

Everything submitted must be original and not contain any copyrighted content.
