First off: Woozle is adorable. 12/10, would boop.
Biggest disappointment is that we don't get to see what a Robo or Doodle Woozle looks like. Is that what the arrow buttons were supposed to be for? Because as far as I could tell they didn't do anything.
I'm not really seeing "it's Spreading" in the game as is. I can see how it might get there, especially how it's explained in your GDD, but i'm not seeing it in the game here.
