I love the game, really it and NSS3 are the best shareware sports games out there at the moment, so jolly well done.
Anyway, how come after a while of hitting the "acceleration" shot (buttons 1+2 together - or button "3" in my case) you stop being able to hit powerful shots? I get maybe your player is tired but your opponent is never affected! About 10 shots down the rally instead of whacking it back at a high velocity, your player hits a looping very slow and short ball. This ruins long rallies, as you can't hit winners with either button 1 or button 2.
Please explain why you have this!
Thanks.
