I agree with gatemaster it is really easy to outsmart the comp and with some people that are actually somewhat smart on the other end would make it a more intense battle
I think if you make a new one first make lots more achievements and second make an avoid mode I tried to see how low of a score I could get and whenever the balls went from left to right it was really hard to avoid hitting them but yeah great game 5/5 and please fix the winner achievement
