Bugs disrupt the game

I bought the game because my night loop Bernd like good, and I wanted to see was implemented as of the humor in the game. The game is similar funny unfortunately only dim some bugs the fun.
For example, dialogs will not play and you only see the text.
In one level, the music track is played twice and added.
Often, the hotspots are set incorrectly. If it is allowed to show itself can not hinklicken there.
One can also, for example, unlock a door several times and the objects that one takes behind, are always there. Although there are no Gamebreaker that make playing impossible, but it bothers very.
For the next game, I would hope that it will be better tested.
