After watching some videos of people playing the demo, I added some hints to the... hints for the riddle. If you enable the tutorial texts, you will see all hints next to the drawer lock when you kneel there.

There is also a hint for the "..." cursor to skip dialog lines.

And finally: I made it easier to open the little door in the wardrobe. :)

Beware:  Old savegames might stop to work and the  solution to the riddle has changed. ;)
