So so easy to play. Drag your finger anywhere on the screen to move. Collect the greens and avoid the white squares. Last as long as you can.Similar to Geometry Wars and retro arcade games, Retro Games X - Geometry Line Runner is an addictive little gem that anyone can play. The first 10 seconds are just a warm up, once the squares start spawning faster it's time to start working that calculator brain to find the best escape. Keep traveling for as long as you can.Enjoy.
