So when you start off, are you actually the cat? Is that why you're short and can't jump?
The whole short story is intentionally vague to be artistically interpretive like poetry. It's a great start for my interactive story writing endeavors. Rise from your bed with C and jump to the sky with ease using Space. CSpace.
Keep playing; the game gets better as I continued to learn and work.

I got a little further, and then was tall and could jump, so that's why I thought I was the cat. But after I got small again, I got trapped in the bedroom by some black smoke thing and it killed me instantly every time the game reloaded. I'll give it another shot when I have more time to try again and play back to that point.
