very underrated game, i can't wait for the next one. original, captivating and challenging. it's not perfect, but I can't stop thinking about it and I'm so excited for the sequel.

It's a good game, and the acting is good, the question system is just a little clunky, especially if you use hints. If you use hints, you have to go through pretty much all the questions to unlock hints about questions you asked earlier, so the conversations don't really flow in that sense. You also can't be too specific with questions or you have to word them a certain way to trigger certain responses. One issue I ran into was that I had to use a hint to trigger specific responses, because the game was registering the question as something I'd already asked. I'm excited for the second instalment to release, it looks really good!

Good acting but a little long-winded and was a little relieved at the end so I could stop typing out questions. However, it's an interesting concept, just think it needs a bit of work for the IMoDD2 when that releases.

It's a proper mystery and in no way holds your hand about solving it. The question-response system is unique and clever game design. However, it grows to be a bit tedious at times because you'll ask a question in direct response to what was said and still get no answer. I've been having to take real-life notes on character info, so for the next game I hope they improve the note system so the player can actually take dedicated notes on each suspect. All in all a fun, creepy experience.

This game is amazing. It is so intriguing and I love trying to get the patients to reveal everything they know. Its very intuitive. Its a very different type of game and I love that about it. I am having a lot of fun and can't wait to find out the story!
