This is super fun! Great job on the art and visuals and really the whole atmosphere! Took me a bit to figure out what I was doing, maybe an interactive tutorial would help this game? I love games like this though, so its a win no matter what lol. It was a little hard to place the objects, I think you should put in a system where it shows an outline on the surface of the planet where you're going to place it, like a grid system but only in the y axis if that makes sense. Overall this was super cool though!
