An ode to swiping. UDLR is a simple, but elegant, swipe based game with a pickup and play attitude. Get as many swipes as possible. Swipe in the correct direction to add time. If you run out of time or swipe incorrectly, it's game over. UDLR:SWIPE (iPhone) & UDLR:TAP (Apple Watch) are two similar, but unique, synesthetic experiences embracing the touch input of their respective devices. The premise is simple. Color = Direction With clever mastery and persistence, players begin naturally matching color to direction.
