Here is an excerpt from Theta and Paralldox on Worldlines' Steam description:

Theta is a little girl who turns left every time she hits a wall. She is curious about the sinking world and discovers a mysterious place, where she picked up a fork that can split her into multiple copies of herself, and from that moment, the world changes forever.

Use the power of splitting to solve puzzles! Split yourself, the universe and something even vaster...

The game is expected to feature 6 main chapters, each revealing at least one hidden truth that already hides within the core mechanics of the game from the beginning. Paralldoxs are under your nose!

240+ handcrafted puzzles, along with meta puzzles and hidden shiny collections that requires power of changing the world.

Hint system and Notebook : You can look up the knowledge you've learnt, or think about the essence of current level in Theta's dream.
