Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0.14/day in the week to Aug 8 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Achei legal. O jogo traz algumas coisas novas, como paredes. Tem também um puzzle: revelar partes de uma carta. Achei bem divertido.
一筆書きパズルです。ラブレターの解読という不思議要素もありますが簡単です。 この系統のパズルとしては難易度は高めと思われます。「このように線を引かないといけない」という縛りになっているギミックが複数あって、基本的には答えがひとつしかないようになっていますが、一問だけ別解で盤面すべてに線を引けたのに正解判定にならないことがあって残念でした。ボリュームは少なめです。一筆書きが好きならオススメ。

Uma carta de amor que você tem que resolver puzzle pra entender o que ta escrito Existe maior prova de amor ?
[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.
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.
“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.
[i]One Line: Letters and Codes[/i] vous demande de traverser tous les carrés (sauf ceux qui seront noircis) avec une ligne qui ne se croise pas. Des éléments (téléporteurs, flèches de direction, clés et cadenas…) devront être utilisés. J'aime les casse-tête et les règles de base de celui-ci, sans être révolutionnaires, sont intéressantes. Le tag « Difficile » ne me semble pas adéquat, car, au contraire, j'ai trouvé les problèmes plutôt faciles à résoudre. Le fait de décoder une lettre est un bon prétexte pour ceux qui souhaitent la présence d'une sorte de scénario, mais, pour moi, cela n'apporte pas vraiment de plus-value. Je donne une note de 6/10, puisque le jeu n'est pas exempt de défauts : [list] [*] Les solutions sont aisément accessibles in-game (voir [url=https://steamcommunity.com/app/1871500/discussions/0/3958162152961992218/]ce sujet du forum[/url]). [*] Le jeu est court. Sans me presser, il m'a fallu moins d'une heure et demie pour résoudre les 40 tableaux. [*] Certains problèmes ont plusieurs solutions. Le programme accepte celles que vous trouvez. Par conséquent, cela ne gênera que les puristes. [/list] Les fans de casse-tête devraient essayer ce jeu. Pour les autres, je vous laisse seul juge.
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!
