A short horror game where you pilot a tiny submarine through an ocean of blood on an alien moon.

Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
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): 3.43/day in the week to Aug 17 → 5.86/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,404 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.

Add-ons
Each DLC is estimated with the same model as a game, then summed — a modeled figure, not reported DLC sales.
Sums Steam only; PlayStation, GOG, Nintendo publish no volume signal, so the true total is higher by an unknown amount.

I like when my lungs are iron
We are one in the blood Simon... Open your eyes
Рекомендую, в целом положительные впечатления. Не как хоррор, а как ориентирование по карте понравилась.

the moral of the story is to never be a bad person or do crimes because if you do, you'll get sent to a really bad scary place. a truly meaningful message 10/10
An ocean of blood and mysteries...
A very short, but great experience. The idea is simple but executed well. The atmosphere is great, played it in one sitting and wound up beating it without crashing into a wall lol. Wound up going back to get the rest of the achievements to round out the 100%. Really fun game, unsure how Markiplier made a feature-length film out of this game that took me 58 minutes to beat, I am curious to go watch and see now. Almost definitely not worth playing full price for. $8 isn't very much for today's indie games, but for one that only has about an hour of time to your first playthrough and very limited replayability, it's kind of overpriced. Just grab this one on sale.
Yup... yup... Okay. Just let my heart rate come down.
MUITO BOM!!!!! Sinceramente, no inicio achei que o jogo seria maçante e que eu enjoaria em pouco tempo. Passei uns dias para entender como funcionava a questão das coordenadas e ficava só batendo o submarino. Depois que eu revi o material escolar do 7 ano sobre coordenadas, o jogo ficou babinha. Apesar de que quando você pega o jeito nas mecânicas, Iron Lung não deixa de ser interessante até o final. Toda a questão com as criaturas, as alucinações e a estrutura se enchendo de sangue de acordo com o quão próximo você está do final, deixam tudo com um gostinho amargo de que realmente não tem como sair do submarino vivo e são, você apenas aceita a realidade. Fico feliz que Markiplier fez o filme inspirado, pq o conceito é realmente diferente e muito legal de se explorar. Concluindo, jogaço 👏👏👏👏👏
waos :O
