Cool game, although it does have some issues to iron out. Firstly, there are some bugs with the power pellets. One time, it got a ghost stuck chasing you while in the "eyeball" state, although I'm not sure whether it was actually able to damage you and it was just a visual bug, but I wasn't able to eat it again. Another time, eating a ghost made it go extra fast when it respawned, and I quickly got cornered and killed over and over. It could be that this is intended behavior, but I assume not.
Also, with regards to the actual growth, it'd be good if the growth graphic was a bit more obvious. As it currently is, it just sits there below the playfield, and you're too busy playing pac-man to actually see her grow. Maybe if it paused the gameplay and popped up for a second when you got to a growth stage, you could see it more easily.
