One of my favorite RPGM games:
The gameplay is a direct inspiration from "Paper Please", where you play the role of a border patrol officer. Abusing your power to pressure npcs to your demands, whatever if you want to simply pass as much npcs you can within the day, or take your time humiliating the npcs. Also there's plenty of unique interaction that will prevent the gameplay experience from getting to repeitive.
Though some translation can feel rough at the edge, you understand what the character is saying, but there is a much easier way of communicating it.
The plot/story is very interesting and entertaining placing itself in a post-war setting, and the character's story isn't flat. Slowly as the game progress you learn more about the protagonist's and other side characters' lore of why they're here and their purpose of doing border patrol.
The art style is great, where the each character have their own interesting design that clearly differentiate from each other. Though the male characters' design (there being like 3 presets) didn't receive much love compared to the female characters.
The sex scenes from the border patrol gameplay are great and animated, but all are the same, and get repeitived over time. Sometimes there will cg scene though there only exist a few, and most are locked until you complete the game.
The side stories after you complete the game feels odd switching towards a visual novel format, not bad experience but out of place in this type of game. This is just my personal opinion though so don't take it too seriouesly.
I would recommend this as must play porn game, as there are alot of mid porn games that feels like a gallery than a game.
