Pros and cons noted. With regards to the cons, however, the way I'm seeing it, is that you want the antithesis of someone who's getting better at their craft (where it's supposed to be easier with time). I understand that you want more challenge across the levels, and that's the angle where you're coming from — I'm struggling to make it make sense.
Coming from someone whose spouse is a model rocketry nerd, that wouldn't make physics sense though...? Like, the plastic bottle ones are typically the hardest to control, and more purpose built ones have better features that allow better thrust and lift.
And... on a related note, we all know what happened IRL to some instances of that final craft we put in (not spoiling). Imagine if that were insanely difficult to control — I think it would be in bad taste, wouldn't you?
