Space is your racetrack. Gravity keeps changing the rules. Run across a luminous spacetime grid in a physics-inspired arcade adventure. Start with Einstein and rescue more scientists through gameplay, mastering their abilities along the way. Swipe between lanes, leap over rifts and slide beneath obstacles as the pace builds. RESCUE THE SCIENTISTS Start with Albert Einstein and unlock three more scientists through gameplay: Albert Einstein - Dash: Race forward with a protected lightspeed burst. Hugh Everett - Portal: Open a shortcut and jump ahead along the course. Marie Curie - Extend: Double the remaining time of your active power-ups with two free uses each run.

Reach Newton's castle, break the seals holding Tesla, and escape across a twisting road pursued by Newton and a looming creature. Collect three portal keys, survive the final barrage, and bring Tesla through the breach. Unlock Tesla and his coil staff, which any scientist can equip for four uses per normal run to clear obstacles and repair broken road.
