Time will tell on whether a game like Qwak can get on well with touch controls...
(I've had some bad experience lately of playing games on my iPod Touch that turn out to be unsuitable without a proper d-pad. Rick Dangerous, anyone? >.<)
I was one of those who ordered and received an original Qwak GBA cart, btw.
Shame my copy had a non-working save function however! I also don't know if I have the original letter and other accompanying bonuses anymore. =[
