Yeah, I guess it is pretty hard. It was very quickly put together, never tested by anybody else and etc.
I tried to make it as fair as possible by insuring spare ammo, making encounters avoidable and not including abundant number of hitscanners. And it is actually possible to make it through without saves (at least I can), not sure about never getting hit. The red keycard door probably glitched out because of the game, it should be working just fine, it's just a lock.
The slopes may be a bit hard to jump, but I made a way out of this since you can skip this part all together by taking the yellow card elevator but you will miss a secret this way.
I hope you liked it and it was not too frustrating for you.
