Well, this was a fun game! The writing is both funny and engaging, and the artwork is sublime.
Now, defeating the siblings is quite hard. The twins' ability to stop you are borderline supernatural. They're always several steps ahead of you, and you're practically always one click away from disaster.
But losing in this game means you get treated with entertaining scenarios at the Madams expense, and numerous defeats have artwork to go with it.
This game has many twists and turns, and it has plenty of replay value with different good and bad endings.
All and all, this is a good game that's well worth your time. Have fun trying to defeat those demonic imps.
