that's great feedback; it's helpful to hear how others experience the game. i wondered if the prison silhouette wasn't clear enough - i'll definitely fix that. the purpose for the 'number on the wall' clue is to prevent the player from knowing the sum of the ages but to indicate that knowing the clue is not enough to solve the puzzle. it's a convoluted way of hinting at the number 13 (since that's the only non-unique sum among the 8 combinations). i adapted this puzzle from another source, and I'm not sure if it works in this context. i don't want players to think they need to SEE the number in order to solve the puzzle, so maybe i need to make that more clear. hearing about your experience is super helpful - thank you for sharing it with me. and thanks for trying out the game!
