About this game

Circular Fallacy is a card-based narrative puzzle game with 3D scene perspective switching.

The story is set in an unknown space where you wake up, having forgotten why you came here, and begin your journey to find yourself... But as the story unfolds, the interwoven layers of time and space make the world increasingly elusive. Can you uncover your original self?

Perspective switching brings unique puzzle-solving mechanics:

In the game, the player's view is not limited to the desktop. As the story progresses, you can break free from the desktop and explore beyond the scenes, discovering new "cards" that will further drive the story and puzzles

Move and combine cards:

You can move the cards you see and combine them to create new interactions

Your senses are separated:

Hand: Touch and pick up objects

Eye: Observe objects

Think: Analyze and examine objects

Using your senses wisely unlocks different puzzle-solving paths.

Dice-check system:

During puzzles, some interactions allow you to use dice for "checks." Different results lead to entirely different branching paths.

Interact with objects in unexpected ways - your choices create multiple valid paths to solve each puzzle.

The unique dice-check system unveils narrative branches that diverge from the main storyline

Every puzzle has more than one solution

Each ending contributes to the whole story

In Ego’s dreams, he always finds himself in an endlessly looping hallway, with no exit and no meaning. Until one day, he tries to escape... only to discover that the world...
