Gravoor

Gravoor was one of those games you'd find in the later days of Flash, a straightforward puzzle box that didn't ask for much time but demanded your full attention. It appeared quietly, without much fanfare from a known developer or publisher, and simply existed as a thing to figure out. You loaded it up in a browser window, and that was that.

You control a small, simple shape, navigating a series of abstract, grid-based rooms. Your moment-to-moment task is to move through each maze, find a key, and then reach the locked door it opens. The interaction is entirely mouse-driven; you click to move your character square by square, planning each step to avoid dead ends. The main objective is to clear all twenty-seven of these mazes in sequence. The pacing is methodical, and the difficulty comes from the increasingly complex layouts that force you to trace and retrace paths in your mind. It feels like quietly untangling a knot.
