Interesting...
...although I think it's closer to being a comic at this point. I realize it can be difficult to animate all the stuff at the same level of quality that you get from a focused sketch, so nobody should subtract your score for that. I have ideas of my own that look nice in single drawings, but that I can't imagine taking the time to animate. So, sympathy right there.
The only comments I have are that it would be a little nicer to have it so that when you press the space bar while the new text is coming up, it would speed up the text-appearing speed, or instantly show the text block; it was a little slow waiting for the dialogue to appear.
I wish you luck on your story, though!
