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 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 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.

A charming little puzzle adventure with an interesting and funny story, likable characters with excellent voice acting, and creative level and world design.
I found this game to be below average. The performance is not good. There are a lot of lag spikes all over the place that I could not find a solution to. The writing is incoherent and dull at its worst, and kind of amusing at its best. I did not feel attached to the overall plot and characters, except one character and their fate. There is no adventure. You walk slowly along a prepared path and do some very very light puzzling at times. But mostly it's just talking to people, do some "fetch quest"-like tasks, or do the next obvious thing ahead of you. You go from area to area for no reason in particular and stuff just happens around you. It feels like the game areas were designed first and then shoehorned into the narrative. The game is trying very hard to be funny, and it doesn't really work. The funniest moment in the game that I recall is a reference to a children's film. You are given a few "verbs" that you can do as the player. You can delete stuff, copy stuff, recolor stuff, or "flip"-stuff (which can have different effects depending on context). These verbs are used sparingly, and when you encounter a situation where the verbs can be used in interesting ways, you will rarely or never encounter similar situations again. In one area in particular there is a small interesting puzzle that requires you to utilize both the recolor and the flip actions to solve it. But the puzzle is easy, and you don't encounter any more puzzles of the same type again. In all other areas, like voice acting, art, and music - the game is not great, but completely fine.

absolute banger
Good game. The athstetic and art direction are pleasing though not particularly stand-out. The puzzles can demand some depth of thought though they tend to be rather simple. The movement is the simple bare minimum one would expect in a 3D game, though it doesn’t require any more than that to function well. The music is pretty good though none of the tracks really stand out. The high point of the game is the characters and story. Oh my goodness the story. The is one the exceedingly few games where iv’e felt genuinely emotional sadness. The personality in characters helped me get attached to them, though I will say that some have more than others. Definitely recommend this if you like story central games.
I finally understand what's happening inside my phone during an OS upgrade
Pretty fun little gem of a game
Really wish I could rate meh... It's an okay walking simulator but nothing exciting. The white bread of gaming.
lowkey might've cried a little bit towards the end. whoopsies. DEFINITELY coming back to 100% when i have the time and motivation... i'll never forget you, os9.
Игра понравилась. Разработчики явно вдохновлялись The Stanley Parable и Порталом. Есть интересные механики, хотя их потенциал реализован далеко не на полную. Головоломки очень простые, проходится на чиле. Жаль, что нет New Game+ или хотя бы возможности наделать много сохранений. Есть в этой игре развилки, где не очевидно куда продолжение основного сюжета, а куда нужно забежать за бонусами. Так вот когда ты сворачиваешь в сюжет, то зачастую назад за бонусом вернуться уже невозможно, из-за этого недополучил несколько ачивок.
好玩。很多有趣的小设计和对话。
