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): 0.29/day in the week to Aug 24 → 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.

I really liked this game, but I also have to caveat that it's not the smoothest to play. I love quirky sim games like this - strange horticulture/antiquities, trash goblin, restory, etc. - and when there's a lovecraftian elements, even better. This game has all the potential to be great - but it falls short in a few areas. 1. The instructions for how to use the diagnostic tools are INCREDIBLY confusing. The humor wheel in particular - while incredibly useful and a staple of my playthrough once I understood how to use it - was so confusingly explained, I needed to look up a reddit thread to help me parse it. This is due to the fact that the BASE mechanic - the dosage explanation - is incredible convoluted, making everything that follows difficult to parse through. Once you do, however, treating patients does become much easier and more fun - however, that does not cover for issue 2: 2. It's way too long. The story here is very similar in tone and setup as strange horticulture/antiquities, but whereas those two titles had very quick days and frequent 'events,' Do No Harm drags where it shouldn't. Nearing the end of my run, I was blazing through over a dozen patients a day with nothing really happening, which made the gameplay loop a little boring. The threat of the entity at the end was not clearly defined, and I hardly ever felt it as the mechanic to battle it was confusing and not really necessary. All of this to say - I still enjoyed the game. If you have an itch for a quirky spooky sim game, this is a good one to pick up. While it could certainly use polish, it's got style and heart. Maybe wait for a sale, though.

Good soup.
Fun game. The art is very nice, and gameplay is a nice kind of repetitive (though I can see some people not liking that). I've had a lot of fun with it so far and I do recommend it, though I feel my complaints over it are more helpful than any generic praise I could give. I feel the tutorials for a few items were a bit confusing, the humor wheel especially which I've yet to get a hang on, and trial and error with these aren't supported given that would (most likely) kill the patient. The game needs more accessibility options, especially one to reduce flashing or other screen effects. While they do have a warning at the start of the game for this it is the generic warning most video games have, and they don't have anything to account for it. They only added something to help deaf/hard of hearing players with an audio important section of the game around may this year, and I don't really see why they would account for arachnophobia in the settings but not flashing, which could fairly easily be lessened in a similar way by the developers. I get some peoples arachnophobia is bad, but flashing is a thing that could very well kill certain players, and I don't think it's an unreasonable ask for a bit more than the bare minimum. If screen effects truly can't be lessened in any way I feel it would be nice to have a more specified warning at the start of the game that didn't fade out after a certain amount of time, and that actually gave players a moment to read. Text can also be rather small and hard to read, and has no options to make larger in settings, though this usually wasn't too big of an issue as most important messages have you manually click through them and don't just disappear, giving me at least some time to figure out what was being said. Overall though it's been a fun play and I would recommend it to those who enjoy the lovecraft stories/vibe, and games similar in form to papers please. These things didn't impede on my fun too much, but that's just me ofc and they might be dealbreakers for others.
中世纪庸医模拟器 快治死的病人直接让他滚出去 快死的病人也让他滚出去 说不出病情的病人也让他滚出去 用药量大的病人也滚出去 只要别四我这里就好了 别耽误叔叔赚钱 赚钱真是太容易辣! 但是赚钱只能用来加药真的太伤了 没啥动力赚钱 给病人治病花费药 然后挣的钱又要去买药 但是如果我一个也不治 药就不会消耗 也就不会消耗钱所以根本不用治是吧( 治人=亏钱 布好 我的良心
I like this game quite a bit, could use some tune ups with controls and clicking placements, perhaps ability to do just keybindings if possible but the art, story and gameplay is nice.
Todo es muy repetitivo, y la variedad de personajes es baja. Las "anomalías" a veces son tan sutiles como un cambio de color o un sonido, y pueden hacerte perder la partida. Las mecánicas mas avanzadas están muy muy mal explicadas, y tienes que ver vídeos para tenerlo mas claro. Ya no es aprender a cómo jugar, es tener que estudiar para poder hacerlo. Y simplemente, no me apetece tener que hacerlo.
girl of course i missed anomalies im focused on curing my freaking patients .
Сеттинг хороший, задумка классная, реализация хрень. по какой причине я должен иметь мотивацию к поддержке хоть кого-то из персонажей кроме совы? что склоняет меня убивать рыболюдов? что склоняет к поддержке священника? какого лешего происходит в обоих финалах (которых по факту два, в остальном у тебя только спрайты персонажей разные)? и я понимаю их суть, но они не логичны в контексте происходящего и статов. советую купить по огромной скидке полапать механики (которые тоже реализованы местами никак).
Fantastic Game of juggling mechanics and obviously incredible art! :] especially with the narrative update. I highly recommend
