i just picked up the demo and am rather enjoying it but there are some interaction/usability problems. see i built my little starter craft and was buzzing around and eventually decided i wanted to rebuild it. now in the build menu i cant figure out how to deselect the part i'm currently holding. most games you'd right click or something. also because i couldnt figure out how to select and then move my crew quarters i deleted it and even though i put a new quarters on all my crew was also, apparently, deleted. just some little things that make the builder feel either difficult to use or unfinished i dont know which, or i'm missing something.
