A very cute and charming puzzle game of delivering letters! I like that the sense of community is baked into talking to the residents to find out who the unknown letters are supposed to go to. Perhaps the house numbers should still be shown to ground the player in the world, both in the narrative sense and as a starting point to help the player out in the beginning, because it feels a bit weird not to know the house numbers even though I am a postfrog, haha! The voice acting is superb and made me felt more immersed. All in all, it’s quite an enjoyable puzzle game. Excellent work!
