I played against the AI.

The red "new game" button is too visible. I pressed it twice in the first times, and then I learned to not press it. Perhaps it would be nice to hide it a little.

When the AI has an obvious move like in the case "Ai Hu Hu Hu Hu " , then the AI plays too fast. We made some games a long time ago and we added a minimal delay (like .2 seconds?) so it's easier to understand that you play and later the AI plays. (Also, to make the computer seem smarted, because it has to think a lot :) .)
