To test the AGA libs I wrote a breakout game with them. I found some bugs and the worst was one that crashed the computer when you turned the game of . The most difficult bug to find was a simple off-by-one error, it took me one whole day . It also became clear that the input (keyboard, mouse) sys for AGA was totally impossible to understand. Time for a rewrite and then I will do one more mini game to check so all the things I changed works .
