I think most of them fall victim to the exact same folly that only a few people in our society seem to have realized: space, in all fairness, is actually incredibly boring. Sure, there are a few neat objects in the universe, but all the stars, planets, nebulae, pulsars and black holes round to zero in the unfathomably vast expanses of literal nothing that blanket them. I actually made a level that pokes fun at this belief, but to put it in words: most of the Space Gauntlet submissions make a spectacle of space, treating it as a mere veneer for whatever glitzy sci-fi nonsense they can stuff in there. You also have levels like 'space i guess' that attempt to rectify the retinal, and most importantly, unrealistic nature of Space Gauntlet levels by throwing in some vapid, uninspired "philosophy", itself being none the wiser. 'Planispheres' by Flash is definitely the best level to come out of the contest, because it focuses more on the history of astronomy, which, for most of human history, consisted of just looking up at the sky and tracking what can be seen with the naked eye. That's real space, not the fabrications that all other space-themed levels unwittingly present, fueled by false color astrophotography and science fiction.
