    Controls:
        ASCII CODE 13 - "Return"
         1 -> enable barriers
         2 -> disable barriers

        Keep Tetra, discard Cubes.
Once there is only Tetra, you can progress.

There will be an increase in speed 3 times,
  Then there will be another Signal added.

   You must bring that system to a halt
This objective is imperitive, no alternitive.

    We are wishing you excellent luck.
