What players are saying
Counted from the reviewers’ own thumbs up/down on the 187 English Steam reviews we collected, not by the AI. Valve’s all-language rating: Very Positive (510 of 620 positive).
Players praise the Lovecraftian FMV mystery as ambitious and compelling, with strong acting and story. [1][2][3] Many find the text-input questioning system frustrating, requiring exact keywords to progress. [4][5][6]

This may not be a popular review given the positive reviews....however I feel the points I make are justified. IMODD is a very ambitious game, an FMV where you actually type in the questions. The problem here is you have to type them in the right way, and another thing is it says youve asked a question already, even though the one youre asking is completely different to the one you asked before. Example "do you like …

Reviewing (mostly) every game (or DLC) in my library, part 212: ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️☆☆ (8/10) If Her Story and Lovecraft had a weird little FMV baby, it’d probably look a lot like The Infectious Madness of Doctor Dekker.

I am posting this as a positive review, but I am going to focus on vital aspects that can make you hate the game. Then you can decide if you should buy it or not. 1) Mechanic This is a very interesting game with a mechanic that allows you to concentrate on the story. I did not find it difficult and strongly disagree with most of the negative reviews. Most of them were written out of lack of patience and inability to …

Very cool concept, but I agree with the negative reviews. The game really wants you to ask very specific questions and is not intuitive at all. You can know that you caught a character in a contradiction, but you can never express it as the game wants you to.

Prologue: "The Infectious Madness of Doctor Dekker". Pretty solid FMV game with great acting and story. About 15 - 25 hours of gameplay. Recommended at full price and definitely on sale. Pros: 1.) Amazing acting (mostly) 2.) Interesting story with Lovecraftian influences 3.) Great gameplay and idea of a game 4.) Simple to handle and easy to comeback mid-game 5.) Pretty long for your typical FMV-Game Neutral: 1.) …
Summarised from 34 of the 262 public posts collected about this game; every point cites the posts behind it ([n] opens the post) and the split is counted from the posts’ own ratings. Updated Oct 13, 2026. How summaries are made
76% of the 187 Steam reviewers we collected recommend The Infectious Madness of Doctor Dekker. The complaint that keeps coming up: parser requires very specific wording. Deal-breaker or nitpick?
Critics, per Wikipedia
On Metacritic, the PC and Nintendo Switch versions received positive reviews, and the PS4 version received mixed reviews. Adventure Gamers and Rock Paper Shotgun both compared the game to Her Story. Adventure Gamers said it adds a few new twists and includes more dialogue, and Rock Paper Shotgun wrote that it does not always elegantly succeed at meeting its goals. For example, reviewer John Walker said that the game's parser misunderstands some obvious questions, though he felt that game remains "often very interesting" despite its limitations. Adventure Gamers concluded, "The Infectious Madness of Doctor Dekker is engrossing, disturbing and erudite, and though it's a little lacking in plot…

The slow progression was a major turn-off for me. Don’t get me wrong, it’s not a horrible game, there’s definitely a great concept here.

positive · AI labelView post →While the game is an interesting concept and an interesting story it lacked on the programming. Inputting questions was very clunky and difficult. It does not allow for any variance in questions. In fact, a lack of a comma when forming a question tripped it up at one point. There was a lack of flow with the story and questions. Some of the questions towards the patients are a tedious, and I was not quite sure what to ask them.

neutral · AI labelView post →The idea is great, nothing new, really...FMV games were popular even through the 90s. What I don't like about this game is that sometimes you ask something that supposed to be logical (clues btw are barely noticeable in the conversations), but they all lead to 'I don't know...have no idea', etc...I literally ask almost the same thing that the hint questions say, slightly different wording and I get into a wall....at least 90s quests were more logical about that, here you have to hit exact words…

negative · reviewer's own thumbsView post →First of all, the thing that makes this game unacceptably bad and tedious that I cannot even bring myself to finish is the UI. The UI is dreadful, to say that the UI is bad is an understatement. Unreadable texts, unseeable mouse cursor, and generally unintuitive UI. If you really like the game and its concept, you can get through that horrendous UI. The story is bloated with useless questions, they are optional but I couldn't feel interested enough to even try and finish it. I expect more…

neutral · AI labelView post →First of all, other reviewers have mentioned that the text parser is often non-intuitive and finicky, and I found this to be true. Overall though, I don’t think this detracted from the experience too much. I fell into a satisfactory pace of asking the questions that initially struck me, then using the hint system to guide me through the remainder. The suggestions felt more like having a helpful assistant rather than cheating. I do enjoy how the game wasn’t too prudish and rewarded some offbeat…

neutral · AI labelView post →At first I was put off by the lousy 'parser' system, where there was no real freedom of questioning. The game wanted us to ask 'exact' questions according to what was programmed. For example, instead of responding to the question "why did I come to your house?" the game would only respond to "why was I there at your house last night?" Since the questioning system is not AI based, its understandable its like this. Ultimately, you will learn that the easiest way to move forward is only by using…
positive · reviewer's own thumbsView post →I'm sure there's a cool story in here. Unfortunately the game's free text input mechanic is unbearably boring and clunky. The characters seem to respond to keywords, ignoring any context in your input. Their answers are usually nonsensical with respect to what you've actually asked and constantly reveal that there's nothing more going on under the hood than a look-up in some sort of internal database based on one word in the sentence you've typed. It makes it really hard to feel any immersion.…
negative · reviewer's own thumbsView post →"we're going to let the user ask open-ended questions but they have to be precise open-ended questions or else we say nothing." Seriously, I cannot, I cannot emphasize how much I think this game is a waste of everyone's time. 85%? BULL. Absolutely every review in the positive gives a pass to the text interpretation having 'some issues.' Some issues? This is gross. This is an affront to human intelligence. This is GPT-0.0003 . Seriously, ugh.
negative · reviewer's own thumbsView post →The acting is great and entertaining to watch. The story is disjointed but passable. As a game, it is disappointing. You're supposed to type in questions Zork-style, but that quickly becomes tedious as hell because the parser is so bad. "Do you believe in spontaneous combustion?" elicits a no response, but "Is spontaneous combustion real?" gives you a answer. That happened enough times that I started just using the pull-down menu of questions which then makes the game just a movie. For a…

I primarily bought this game because I am a therapist and I love detective games so I felt that it was a nice blend of my career and my interests. I'm always leery of FMV games, but this is very well done. Dr. Dekker doesn't struggle with phrasing and will give the player a lot of leeway with how you ask questions. You can even be playful with it. At one point I decided to quote a scene from the Big…

English is not my first language, so if I misspell a word, I'm stuck; if I ask a question without proper grammar, I'm stuck.

It's fun finding enough information, but keep in mind that, as the game warns you, trying to 100% the characters is very difficult and could "drive you mad". If you want to do that, just use a guide.

The persons are easy to believe and they seems to be real. The mechanic of the game is original and a little different. Really to ask questions, to type them.

Meaning, this murder mystery has a different murderer depending on how you interact with the characters. This makes no sense to me. What makes a mystery satisfying is its solution.

If there are multiple right answers, none of that works. Maybe I'm…
