Well done.
The artwork could have used more effort. The sound is good, and the lessons are hilarious.
In case anybody cares, here's some extra German phrases:
"Ist diese zweite, winzige Toilette für die Zwerge Ihres Landes?"
Is this second, smaller toilet for the dwarfs of your country?
"Sie sind der sklave von Ihre Selbst furcht und dummheit"
You are the slave of your own fear and ignorance.
