Spacetime is unstable — every 7 to 12 seconds you're bumped to a random, distant, unhelpful part of the maze.
On a step count or a timer, the system glitches: you're held in place while the maze redraws around you.
Certain passages are barred by clockwork gates that only open on their own beat.
Requisition upgrades at fallen armories, then see how you ranked against every other gladiator who ran today's ruins.
Reach any of three windmills for a different ending, and chart a route with a cart-path shortcut.
Something blind lives in the water with you, and it hunts by feeling every move you make.
