We’re definitely getting into a tangent here, but I tried that for Miss Gosling’s Last Case (in the current IFComp), and it takes some rethinking to figure out how to make puzzles that aren’t obvious from the choice of verb but imo it’s definitely doable. Or look at limited parser games like last year’s The Vambrace of Destiny, where there are exactly 26 possible actions corresponding to the 26 letters of the alphabet.
