Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Every market we collect.
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): 6.14/day in the week to Aug 22 → 6.29/day in the week after.

Add-ons
Each DLC is estimated with the same model as a game, then summed — a modeled figure, not reported DLC sales.
Updates
Build ids and update times come straight from Steam's PICS — the same source SteamDB reads. Patch history grows as we record new builds.

Reviews
This game is cool, but its age shows. I am too used to repentance +. Only 1.49 though. Also I give my thanks to my wife’s boyfriend for getting me this.
Where's the Chinese？
Игра своего времени, сейчас является лишь памятником флеш играм и в целом плохо ощущается сейчас. Не рекомендую к покупке, лучше купить актуальную версию Айзека

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.

以撒是最好的肉鸽
Hay tantas cosas malas que no sé por dónde empezar: mala optimización, MUUUUUCHO desbalance entre items y enemigos (haciendo que algunas partidas sean imposibles), el bug de la resolución y, por lo que veo, también de los logros Ni hablar de jugar con personajes como blue baby, es mas fácil encontrar agua en Marte que un corazón de alma en este juego
"Isaac and his mother lived alone in a small house on a hill..." Se você leu com a voz do narrador, amigo, já era
odio este juego

ill play this game for 5 years straight and STILL find secrets that i never found out about 10/10
I cannot recommend this game to anyone EXCEPT to the hardcore TBoI andies. The real ones. The kind of guys that 100%'d Repentance. The type of beasts that feel the games are now a bit too easy. Eternal mode is your pick. If you're not one of those people, just play Rebirth (Repentance). I got reminded of the frustration of being so bad and incompetent at the game to take damage from a pooter and got reminded of the satisfaction and joy of achieving something great like the "X Boy" achievements or beating a final boss in eternal mode. I love Isaac. I ♥♥♥♥♥♥♥ loved this game, but I also ♥♥♥♥♥♥♥ hated this game. I will NOT become back my money.
