Hi Andreas --

There is actually a plan for what to do when one gets stuck. There 
will be a "hints" button on every page, and when you touch it (if 
you've tried already), the system will show you (via event recorder 
and a scripting area) how to do it. All of these are revertable 
(thanks to Ted and Scott).

This double tactic (of doing the game first and then using a hint 
demo if stuck) seems like it will be good for the kids and is likely 
to work fairly well.
