How it feels

A quiet, deliberate puzzle game where you slowly and methodically construct formal logical proofs, feeling a satisfying click of clarity when each step falls into place.

What players say

Players praise the polish and the logical challenge, comparing it to Turing Complete, but many struggle with the tutorial: it is confusing, bugged tooltips block text, and the difficulty assumes prior logic knowledge. Long-time players want more sections and a reset button.
