Oh no! Sorry to hear that! Is there anything you might suggest to help better allude to how to solve the codes? Anything you wish you had to lead you in the right direction?
To allude better, I think it needs something that visuals to show proper hints such as in-order of the amount of the food cans which have alphabets. And another way that I would suggest is a fun narration during the gameplay. It would be mixed well with the game mood. XD
