Velocibox

User Summary You play a cube that races incredibly fast down a box-like tube trying to gather other cubes but avoid the structures along the way. You can press a button to flip to the 'ceiling' or steer to the sides. The graphics are pure abstract, but what makes the game different from others is how difficult it is. This is 'twitch' endless runner, a game beyond difficult: in the time you have taken to read this, you would have died 3 or 4 times.
