A true postal worker needs both persistence and Patience. Outstanding game. I ran into the issues of those who didn't recommend the game. Black loading screens and other various bugs. At time of writing this review, they are gone, Shredded even FlatNine Developer are super active to the Letter, fixing issues promptly. Game development is obviously never an easy thing but this certainly gets my Stamp of approval, especially these sorts of games with so many aspects to them. They are always there to answer any questions (...via hints), talks to and praises those who provides guides and what not (which are very good in of themselves). Listens to the community through forums to evolve the game. Such as, if any gameplay element appear to be a bit confused, like the order of a task to unlock secrets or reveal parts of the story or even move the story along. Acknowledges them and states to strive to sort them out and actually do. The game is so good (as you can probably see from my play time, which this review is cutting into my playtime to be honest so I will be getting back to it, post-haste) and is right up my Pneumatic tube. Liv - the antagonist or is she the a protagonist(.. hmm!) …3 found this helpful
I'm obsessed with this game! Not only because I love being a good mailman in my mailroom sending all my little letters and packages, but because there are so many secrets to figure out with all the crazy citizens of the Isle. I've been playing for a while and there's still so much is left to explore!2 found this helpful

A little bit of cozy plus addicting job sim plus horror (no jump scare) I love it 10/102 found this helpful
Very much enjoying playing Letter Lost. The riddles, the puzzles, the creepy/spookiness. Not too overwhelming horror...big thumbs up!! I have experienced few minor glitches...but nothing game breaking, and the Devs are consistently fixing the issues.1 found this helpful
