What Steam players say
Recent verbatim reviews from Steam — separate from playze.io community reviews below.
Same drills as the prequel with an added mechanic of filling in the blankets of a love letter, with each missing piece being one completed puzzle - but the letter also serves as a hint system: hovering over an unfinished puzzle will display one possible solution for it, so you can match the boards and use that if you're stuck in a given puzzle.
Worth the weight...
“One Line: Letters and Codes” is a slightly more polished version of the original “One Line”. It has slightly different special fields than the original, and is also a bit shorter (30 levels instead of the original’s 40 levels). If you enjoyed “One Line”, then you’ll also enjoy “One Line: Letters and Codes”. The game’s gimmick is a letter whose words need to be unlocked by solving the levels. This mechanic doesn’t really add anything to the levels themselves, but it adds a nice overall touch to the game. Like with the original “One Line” I solved most of the levels by first taking a screenshot of the level and then scribbling over it in a drawing program, separating the parts of the level that are logically deducible from those that rely on guessing and intuition. Just like with the original, this made the game pretty doable.
Relatively simple and short line drawing puzzle game. It is fine for what it is. Score: 5/9
[h3]Yeah this puzzle game spoils its own solutions[/h3] By saying this I mean not a ‘hint’ system, as the devs suggested…You will get the answers whether you want it or not. The game will lock every 10 puzzles until the player ‘decodes’ the letter with all the solutions got so far. The pieces in the letter don’t go by the order. You are bound to get spoiled. The achievements also contain a few of them pretty patterns, but the achievements are not hidden; they are visible in the library page without even opening the achievements folder. The game itself is good. The said issue is just too bad for a puzzle game.
Another 100% Another Review: Bought This game because i Was Looking at the Dev Page After 100%ing Mewsuem Masterpieces. I Thought this game Looked Unique and a New kinda Puzzle Game to try. Did NOT Expect To Somehow get invested in a Love letter Sideplot. Im not Even Joking, every time i would beat 10 levels and go Fill it out, I would Scheme On What the Missing Words Could Be. And then After i Beat Everything? I Aint Going to Say Anything, But....Please Finish All the Puzzles if you play This game. Anyways, Very Good Game, May have to Buy the Rest of New Dawn's games After this One!
