Simple and fun, and interesting! Witch-circuit in the kids room makes it the most comical with sounds.
I'd like to see more and some challenge also in the game (like: Try to not spawn monster that eats you, or leaves the room to eat everyone else, so the challenge would be try to create a specific monster which would be more engaging.) Maybe some receipts could be used in game, like: using much power and blood from cards summons the most hazard beast, and cuteness create some sort of plush toys, etc. --- Anyway, this is a great thing!
