Play Flux (Requires MegaCD) (Program) Online
You're flipping gravity mid-jump while the world warps around you—one second you're running on walls, the next dodging obstacles to a pulsing beat. That Mega CD crunch just makes the chaos more hypnotic.

Flux was a Sega Genesis game that required the Mega CD add-on to run, though it never actually saw a commercial release. It was developed by Sega, intended as a tech demo to showcase the expanded capabilities of the CD hardware. It exists as a piece of that transitional period, a glimpse into what developers were experimenting with beyond the cartridge format.
You control a small, abstract character navigating through a series of shifting, geometric tunnels. The main objective is simply to survive as long as possible while the environment constantly deforms around you. The core mechanics involve precise jumping to avoid obstacles and, most notably, manipulating gravity to flip your orientation, turning walls into floors. The pacing is relentless, synced to a driving, rhythmic soundtrack that dictates the flow of hazards. It feels like trying to solve a puzzle while the pieces are actively trying to escape you.
