Really liking the idea of a speedrun maze runner, and kittens are always a plus!
Two small feedbacks: 1, A sound effect for when the feeding happens would be nice, so you don’t have to rely on the UI (which blends into the maze walls!)
2, A better acceleration system instead of a fix speed (or a more fine tuned one if it exists already) would help the play feel not be “tainted” with the tight 1 block gaps.
Otherwise, nice game, nice concept! Cool dramatic piano sounds!
