That was cute! The premise is funny, yet compelling. I especially enjoy the jazzy soundtrack!
It took me a while to realize the rhythm arrows were supposed to align with the line on top of the box. I had initially assumed the arrow was supposed to be inside the box.
I'm not sure if the mechanics mesh with the premise very well. It seems like I'm supposed to be encouraged to move slowly, using my limited noise resource to avoid obstacles, doing the minigame only as a last resort. However, acing the minigame (which is fairly easy) causes no noise to be built up, so it's potentially less risky to blind run everywhere than it is to use meowing at all.
All-in-all, good work! Congratulations on the submission!
