I did not like the aiming system on the wii version, I believe it was an arrow that just moved back and forth and you just timed the hit to adjust your aim? What is the aiming like in this one?
for the strenght of the shot:
Buttons: classic golf stuff, press A once to start the meter press it again to stop it
Touch: touch the ball (yeah!) pull to the power lvl you want (also shown on the indicator) and let the stylus go
Aiming:
Slide: well, left and right to aim
Touch: touch the outter ring and aim at any direction you want. quick and cool but not as precise as the slidepad.
while you set the strenght for the shot ther is a little yellow dot hoovering over the ball from left to right which indicates the spin the ball will have for the shot.
i haven't played it that much right now, but there is really a nice list of unlockable stuff.
just bought (in game coin-system) a 8-Bit Soundset. hurrr! kind of a bummer they didn't add some archivments. ah well at least they added medals.
