Sprint and jump through challenges in a strange space world without falling off. Play as an alien running through a tunnel filled with obstacles and holes. Run along the walls to change gravity and find creative ways to get yourself through the tunnel. Watch out for tiles that may fall out from under you and holes in the tunnel! If you fall into one, you will be lost in space. With different playable modes and over 300 different levels available, there are so many ways to climb, sprint, and explore. Test your skills and endurance with endless mode, or challenge friends online to see who can get the farthest!
