You're making a wish into a Magic 8-Ball
This is a question dropped into a Magic 8-Ball: you shake it, and some answer floats up. Claude knows nothing about what you're picturing, so every gap gets filled with a guess. This is where hallucinations start: decisions made with little or no context at all.
Is this the game you were picturing?
Make me a whack-a-mole game. It should be fun to play, not too hard, and well designed.
