Non Euclidean Doom Map?

[Trusty McLegit]

I remember playing an awesome 1 level wad that heavily featured non Euclidean geometry. For example you start at the top of the map and work your way down. But by the end of it you end up back at the top again. And there was a circular hallway that circled 720 degrees before finding the exit. This wad existed before portals were added to GZDoom so it did all this with line teleports. Any help finding this map or any similar would be super appreciated!

I know there's a single-level PWAD named Impossible: A New Reality.
Not sure if you are mentioned this PWAD.

[Trusty McLegit]

Yes I think that's it! Thank you so much!

[Wally0222]

You're welcome.

PS: I wish there's any similar level like that PWAD.

I actually really want to make something in a similar vein. I've only made a couple maps before so idk how long it'll take, but that's actually why I wanted to find this map for inspiration. If I ever make something I think is decent I'll send you a link!

Sounds interesting, and I quite excited about this. Take as much time as you need, you can do it freely.

PS: I'm busy in real life sometime.
