You need to make the power ups stand out more, I spent the first two levels dodging them because I thought they were bigger, slower bullets.

The boss as the end of each level, I think it was a boss could do with health bar, so the player knows it's an important thing to shoot.

A part from that I liked it.

I might be missing something, but i just couldn't get a long conversation going. The only thing she responded too was "Hi" and "How are you?". So I guess she still needs a lot of knowledge.
It also wasn't clear where I had to type. My first instinct was to use the lower right box to type, I thought the white box on the bottom was decoration.
Higher quality pictures for the monitor would be nice.
This seems like it has good foundation. Good luck with improving it.
