you captured some EXCELLENT vibes in your tracks for this jam — "Build Your Rocket" has such a good rhythm to it, and "Open Space" feels so fitting for exploring the vacant cosmos... ^-^
personally, "Open Space" is fine the way you composed and arranged it. your videogame concept treats outer space as a liminal section, a transitional point between major events and locations that might occur; the subtle vibes that slowly evolve through the arrangement fit that very well!
