3rd endless mode

The Third endless mode is another endless mode (also being the last checkpoint in the entire game (if you don't count any hypothetical loops of endless mode), preceded by the 2nd endless mode.
 * It is reachable at 28,000 distance. However, this will not have an ending, or even lead to the 4th endless mode, as the Repeating Room Glitch will occur past a distance of 30,000 or stage 30 (2nd stage harder variant).
 * If you did the Random Rooms Glitch, it will be re-doing the same room (only one room) over and over again (which will be stage 30).

Only a dozen players have reached this, according to the Smash Hit page..

It is IMPOSSIBLE to reach the 3rd endless mode without the obvious Random Rooms Glitch. (Unless you stash on ~1,250 balls or more, which can only be accomplished by using the Ball Grinding Method or a VERY lucky Room Generator.)

 * "what??? checkpoint 13??? i have never got to checkpoint 13, there are checkpoints 0,1,2,3,4,5,6,7,8,9,10,11, infinity. If infinity is checkpoint 12, then there isn't a checkpoint 13. 5-5 is a fake level. My highscore is 35100 and if you use [the random rooms] glitch abuse you can get my score."
