Original idea in a polished format — good story, fluent mechanics, beautiful transitions and animations. You also nailed the overall atmosphere and the dot mechanics. They are very intuitive.
There should be more checkpoints, maybe after every sentence. There is a small typo after the predators: "Use the tots." It would be more comfortable to hit space to continue instead of enter because my finger is already over that key anyways. I, up, down, and push mechanics are fun, maybe you should add more like these. The difficulty curve is a little bit jagged, especially in the end.
To summarize, this was a pleasant experience. Good job!
