About Catalyst

ABOUT THE GAME


Catalyst is an unsettling interactive narrative into the world of psychotherapy. The story is told through newspaper articles, notes left by a disgruntled secretary, unwelcome letters, audio tape recordings and a unique journal that evolves throughout the game based on the player’s own insightful analysis of an unusual therapy session.

THE STORY



After the mysterious death of Dr. Pokorny, Dr. Novak, relatively unknown by many, takes over the illustrious psychotherapy practice. At the same time he inherits Mrs.Ruzicka, the secretary of the deceased psychologist. In the hands of Dr.Novak, the practice is less then flourishing.

One morning, Dr.Novak receives a box of audio tapes – Recorded psychotherapy sessions to be exact – and he is asked to listen to them and give his insightful analysis of its content.

Sadly, things take a turn for the worst for Dr.Novak. His troubled mind seems to be getting the best of him...Or does it?

You decide. You are this psychotherapist. You are Dr.Novak...And your task is to carefully analyze and give your insight on the recorded therapy sessions.

Ultimately, your answers will determine your own fate, Dr. Novak.

FEATURES
Fully narrated psychotherapy sessions by Joseph K. Krachtovil himself.
Three different endings based on the player’s insight.
Interactive desktop with controllable timespans making days shorter or longer.
Immersive storyline delivered to the player via letters, notes, journal entries and audio recording.

In this immersive visual (or better say audio) novel style game you play a psychiatrist exploring the mind of one devious patient to find out, that you have explored your own mind as well. Thought provoking experience! #casual For more quick reviews please [url=https://store.steampowered.com/curator/6972871]follow my curator[/url].

Not a game I thought Id play. But I found myself more and more wanting to hear what the voice on the tapes was going to say.

I played it all in one sitting fresh after installing it, kind of forgetting that I had bought this and just looking for something to play one Sunday evening with everything else taken care of, not knowing what to expect after simply rolling a die. At the very blind circumstances that I had that would be very hard to replicate, my experience was... interesting. I thought at first it would be drama or mystery, then, it became clear as the game progressed and I wanted to be right to badly that I kept playing. Well; I was right, but it was also a nice implementation of a good story. Stellar voice acting! Really sells the whole thing. One thing that I gotta say is that, despite the game being intriguing and drawing; it's not scary. Not in the slightest. Also, the protagonist could have been better. It was hard to relate to such a... guy; and without relating the diary becomes less meaningful. At horror, you sometimes root for the monster and it's fun to do so, but the protagonist should also be 'root-able' if it makes any sense. Maybe it would have worked to make him less of an irredeemable loser?

A fantastic little interactive story with a bad and confusing ending (I think...?). I mean it's not even clear to me whether the game even ended because the days seem to just continue on indefinitely with nothing happening. No credits, no return to the main menu, absolutely nothing that would normally indicate the end of the game other than the voice on the tape saying, "This is the end," which is not sufficient to signal the end of the game because it's a completely normal phrase that fits the context of the tapes. I just let the game continue through several more days, unsure as to whether continuing to play for several more days would make me an idiot or whether quitting because nothing was happening would make me impatient. If that's the intention, well, "clever meta" doesn't necessarily mean good game design. But if we disregard the terrible non-ending, the game was great. Well written, with fantastic visual and audio design. The waits in between tape sessions, notes, etc. help with the pacing and add to the overall experience. It gets better as it goes on, particularly by the third tape. Other than the ending, it was a great game and I really enjoyed it. And it seems like th…

The human mind is a mystery and this game helps you feel like you can solve it! Lots of fun and an interactive narrative that can't be missed! https://youtu.be/2pa7HJBld5Q
