Thanks for the massive amount of useful bug reports! Our bugtracker is extremly filled up with bugs, user wishes and things which have to be reconsidered. Going into details right now would be a bit too much…
As the Win32 version is also our main development version, there wont be any updated versions for GP2x Wiz and GP2x until things are fixed.
Count with a better release in three to four weeks.
In the meantime, enjoy playing!
