With the new 1.1 update to Cube Runner, developer mode has been enabled, turning off collision detection. This basically means you can go through the cubes. With stupid friends, you can play Cube Runner infinitely, and when you turn off developer mode and give it to them... they fail at going through cubes. It's a fun trick, try it by opening Cube Runner, going to Options, then Settings, and turn on Developer mode. Turn it off the same way. http://www.youtube.com/watch?v=cc7lT7hBYDA SEE THE VIDEO!
