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/day in the week to Sep 10 → 0.14/day in the week after.
Reviews, worldwide (the counter carries no country): 0/day in the week to Jul 30 → 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.

下载文件大小是4G,下载完,整个游戏文件有30G,牛逼啊,这是塞了些什么神奇的东西~,不过游戏开头挺有意思的
the quality. the premise, the gameplay, everything this game has to offer makes it an amazing contender for a huge indie title, though its still so unknown and underappreceated its mindboggling. play this game

worst ♥♥♥♥♥♥♥ puzzle game I ever played.
An extremely charming, well-crafted, and fun little game with a good amount of puzzle challenges, neat characters, and an original story that borrows aspects from the original Tron film. It felt like I'd watched, but also participated in, a long movie. Pretty cool.
played the demo before the game came out and enjoyed it so much i picked up the game when it released! took me a few years to actually get around to playing it, but it was a really fun experience. plan to pick it up again in the future to 100% achievements.
OS9, my love.
好玩。很多有趣的小设计和对话。
przyjemna gra z ciekawą fabułą
这游戏还行吧,但我不建议买,为什么呢?看看别人的评测能发现大伙没感觉到meta元素在哪,因为这游戏的meta藏在了全收集里面,就算全收集了还得猜剧情,所以不如去网上看up主的解说。
