This is a game about postman who has to deliver last 10 letters.
This game is primarily a "walking simulator" genre. You only have to click on mailbox and don't get caught by the enemy.
My idea of the game was to make a small "Party horror game" where you can watch your friends play and compete who can beat the game in better time, but you can also play alone. It's inspired by a game in which you have to collect 8 pages, but instead you are delivering 10 letters which are randomly chosen from 50 overall.
