Morse code? Dunno. Probably just a glitch. I'm guessing these useless portal spaces were left over from a previous version of the level, or a removed easter egg.

@Otto4242 Try to transmit it using a morse code decoder or SSTV image.

Sounds like the tractorbeam keeps dropping you and immediately picking you back up. Might have something to do with the fact that using it dooms the player.

I investigated this while compiling the map.
Nothing.
