What an exercise in restraint (and I admire the "cheat" in 1D, craftier indeed to re-turn)! I'm impressed that most of these have sensible surfaces, even when they're comically absurd ("Owl's Law" in 2D). The only one I didn't love was 3D, though I'm impressed with the wordplay of "rolls dry" there—and again, you had MAJOR constraints to deal with!
