However, only 3 out of 5 chapters in the demo contain proper combat, so we’ve made a decision not to immediately overload the game with all the new stuff we’ve prepared.

This is an abstract, chaotic and meaningless world. A man embarks on a strange adventure in pursuit of absolute power and truth. He becomes the protagonist in the story, a player. In this world, anything is possible. Many things have no explanations. Just accept the present and solve the problems. In this confusing and difficult journey, perhaps something can be understood until the end, or maybe there is still no knowledge or gain, and all the efforts end up in vain.
