To install Vexed transfer the game itself (located in Vexed directory)
to your device:

 vexed-lowres.prc - will work on any device. Does not support hires nor
                    fancy colour graphics.
 vexed-hires.prc  - requires high resolution graphics with colour device
                    to work

You have to install at least one level pack. Check the "Levels" directory
and choose some (or install all of them - these are pretty short in bytes)

If you are about to send the *.prc over Bluetooth or IrDA, remember to
quit the game first, or the new version will be silently dropped by
the Palm OS and you'll have to repeat this step over again.
