I followed the links and got to this site:
CREATONIA / Gameplay
Download the correct version, which for the tilt would be the ppc version. Dont run this file on your tilt, this is the installer file for desktop. Run this exe file from your desktop with your pda/phone in its cradle. Activesync/mobile device center should install from there.
If you dont have access to a cradle or usb connector, and u have activesync installed you can still run the installer and it will place a .cab file in c:/program files/Microsoft activesync/Creatonia. Transfer this cab file to your device and open it on ur device to install.
Watch out its 13MB. That is unusally large for a ppc program. Im not sure how much memory a tilt has, but if u have a microsd card, definetly install this game there.
