Ah I still have that build, I did not do the video yet because you said some music was still being added but I can use the current build if you like.
You're free to play the current version of the game. I was planning on adding music eventually, but I have yet to receive anything from the composer who wants to do the music. It's very likely that the future update I'm currently developing still won't include any music, and I have no idea when (or if) Dark Space will eventually have music.
