This was a fun take on the "Papers Please" concept with great art and nice little interactions between the characters! The "vowels matching last digit of the badge number" did, however, feel like a very strange way to increase difficulty; it also raises the question of whether "y" counts as a vowel. I wonder if maybe the characters' heights that the game already gives you could be the next level of difficulty instead? Overall, I had a great time playing through this one!
