How it feels

A stark, unforgiving puzzle-platformer where every move is critical and the only reward is the grim satisfaction of surviving a world built to break you.

What players say

Players enjoy mixing platforming with logic gate puzzles, calling it unique and educational. They find it challenging but satisfying, though many complain about jump controls feeling inconsistent and the game running heavy on mid-range laptops. Players split on whether it stays casual or gets frustrating.
