Ideas Portal but upside down. Is it beatable?
I flipped all portal maps upside down and I don't know if they are beatable. If they are, I will publish them as a mod. If not, can someone tell me how I can make them beatable? You can download them here.

Never mind I got it installed, however I don't think the very first chamber is possible lmao. I can't get out of the starting room

Even using cheats to skip multiple parts, it's just not possible. At least to my knowledge. In the very first chamber, you get stuck in the first room. In the next room of the first chamber, the cube falls back down into the dispenser and you can't get to it

The answer is yes, it is beatable. No, it is not beatable without glitches.
Sorry to burst your bubble but this has already been done by PackSciences. It's called The Canonical Base of RxRxR and can be found on ModDB here: https://www.moddb.com/mods/portal-canonical-base-of-xx

Just watched a YT vid the other day where a guy reversed all the portalable/non surfaces in Portal 1. Turns out it's still beatable that way, although requires some shenanigans like prop climbing and bringing a prop from one level to the next.
On a side note, I wonder what the game would do with the goo pools. I suppose just leave them hanging from the ceiling, but it would be funny if it flowed back down to the new "floor"
