Dirgelicious: No, I haven't ever made a Flash game. But this isn't a game anyway, so what does it matter? I'm not going to give extra stars because it's someone's first try. If I wanted to draw I'd open up Paint. This doesn't even let you draw in color. 1/5.
Sorry, but the standards for a school project are not the same as for a game you want people to actually play. And even for education purposes, the questions at the end should give some kind of feedback so you know if you're right.
The computer happens to play at about my strength, which is good. And the computer at least doesn't pick the same moves every time in the opening, although it sticks to about 2-3.
