Prices
The United States storefront in every case, so this compares stores and not countries.
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 Aug 17 → 0.29/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.

Чудова гра.
Норм гра, є муторні моменти, але добре проходиться якщо розібратись в механіці. дуже атмосферно. за еро-пасхалки окремий комплімент :)

Super jeu, l'univers est génial. la maniabilité n'est pas extraordinaire mais on finit par s'y faire. j'ai adoré le système de parade plutôt bien conçu. Mais le temps de latence pour charger son fusil parmis 5 ennemis est atroce, et il arrive que l'on rate les échelles quand on saute pour les attraper. Mais ça reste un super jeu.
Too hard and unfair. Ambush by 2 or more enemies, the player don't have enough time to respond. Keep seeing game over screen. Easy mode still deal too much damage. One turret pop out take away 60% health. luckily most check-point is close by. Can't change weapon after pick up. Normal shotgun rate of fire slow, get killed by fast flying drone. Pros: Pixel art look very good. The Saw-off shotgun+easy mode let me finish the game.
What a gem! If you still remember the Action-Adventures you played in your childhood fondly, THIS might be just what you need. Just remember that you died a lot when you were fourteen too. And had WAY less checkpoints. So far the story is pretty interesting and the pixel art is absolutely beautiful. In case someone involved in the game reads this: I could iron out a few mistakes in the german and english translation (free oc) if you care. Just drop a note. o7
too bloody hard even on easy mode, hate it and myself while playing it haha
完全不知道作者做这游戏的目的是什么,该游戏主角性能孱弱,敌人却个个攻高血厚机动性强,流程中充斥着各种地图恶意及初见杀,再加上游戏严格的资源限制,我不理解我有什么理由给出好评。当然作者提供了简单模式,虽然简单模式能够正常游玩了,但该模式仅仅调整了伤害数值,相应的恶意一分不少。不仅如此,游戏的中文完全机翻,按键设置也不能自行更改,因此不建议任何人尝试。
