Thanks for saying so! Schu and I were talking about interpretations of the objective. I think a lot of people, myself included, interpreted it as "your core mechanic can have multiple outcomes," when it might actually be, "your core mechanic can DO multiple things." The difference is that the latter allows you to make informed decisions about how you choose to incorporate potential penalties into your play style, while the former... doesn't really involve choice at all, because you have to do to what you have to do no matter what. I envisioned screeching originally to have multiple effects on the environment (manipulating enemies to break obstacles, for example), but it ended up seeming too busy, so I stripped it to its essentials, which, admittedly, may have missed the point of the challenge.
