How it feels
A sleek, minimalist rhythm game that demands focus as you block arrows to a pulsing electronic beat, with a deceptively simple premise that grows punishingly challenging.

What players say
Players compare it to Super Hexagon more than a rhythm game, calling it a reflex challenge with simple arrow inputs. The difficulty is high even on easy, and the music serves feel rather than gameplay. Some note the visual cues are vague and that audio can be ignored.
