Players control a small, cube-shaped character that moves in a spiral motion on a transparent screen. The objective is to navigate the cube through a series of gaps without touching the edges.
The player must time the cube's movements accurately, allowing it to pass through each gap just as it opens. The game runs directly in the browser, with no need for downloads or registrations. As players progress, the gaps become smaller and the pace of the game quickens, presenting a challenging and increasingly difficult test of timing and reaction. The goal is to keep the cube moving for as long as possible, without a satisfactory outcome implied.
