I just downloaded the game, and enjoyed it very much. The AI is good, however, I dont feel that the "hard" mode is hard enough. This is just my opinion, but I was able to take on both bots without dieing several times.
Also, I went to see what your code was like, and found an unpleasant suprise. I assume that you lumped it together for security purposes, but I was hoping to look at the code because, I have never written a full AI, and am looking for examples and refrences wherever I can get them. I understand if you are unwilling to release the code, but it would be nice as an example

.
Anyways, I also noticed that, sometimes, the bots do a full 360 when they find me, and then start shooting. This dosent happen all the time, but I have noticed it more than once.
