Maniac Mansion Mania - 20

This part is a continuation of the last episode. Bernard's sister has next date and she wants to have free house. But the genius doesn't want to go out and she has a trick for him. But I won't tell you what's this. There isn't a problem with the technical gamedesign or with shorter lenght but the problem is poor implementation. For the favourers is this game a duty but to other players I have to say that there are better games in the archive! ;)
