If you go on the 1.00 release on PS4 Disc, you can use a usb keyboard to skip levels in the dimensional map by pressing F. It plays the level cutscene of showing up on the map, and after a while of pressing F, you get teleported to Cortex Island, (final map) and can beat the game in less than 10 mins probably. Is it allowed or is it banned?

As per the rules, it's banned.

I don't think this is limited to "1.0 disc", at least I never heard of it ever being patched out the PS4 version, could be wrong though lol

It is patched out
