We're glad you enjoyed it and found your way, the level design and overall control needs some adjustments.
I'm not sure what you mean by jukebox control, but I'm assuming you're confused about it stopping when you're outside the ship. We wanted to play with the idea that there's no sound in space, so you actually can't play it outside as of now. We still have plans to incorporate that idea into the game while still giving the player some audio flavor during gameplay, but it really is a work in progress.
The music that plays in the Jukebox is "Land of 8 Bits" by Stephen Bennet, but we plan on giving more options, and original songs may happen at some point.
Thank you for playing~!
