This spell is so much more useful than it sounds!!! One of my players just survived a purple worm's belly using this!!!

That's a fantastic idea, I love that.

caes, you fall, te haces 1d6 de daño por cada 10 pies de altura. 

• Water does not flood the space: The entrance opens a portal to a different dimension that does not possess native matter. As a dimensional barrier that blocks the effects of the material plane, the water remains outside .
• You create an air bubble: The space manifests with a clean, dry atmosphere. If your group consists of air-breathing characters (like humans or elves) who are drowning at the bottom of the ocean, climbing the rope will take them to a completely dry, floating room where they can breathe freely for 1 hour.
• The physics of the rope: The spell forces the rope to become perpendicular. Underwater, the rope will simply float straight up automatically, pointing towards the surface, overcoming water resistance or currents

Does it work underwater?

Yes, it works perfectly, and in fact it's one of the best underwater survival tools.

When you cast Rope Trick underwater, the following magical and physical effects occur:

• Water does not flood the space: The entrance opens a portal to a different dimension that does not possess native matter. As a dimensional barrier that blocks the effects of the material plane, the water remains outside .
• You create an air bubble: The space manifests with a clean, dry atmosphere. If your group consists of air-breathing characters (like humans or elves) who are drowning at the bottom of the ocean, climbing the rope will take them to a completely dry, floating room where they can breathe freely for 1 hour.
• The physics of the rope: The spell forces the rope to become perpendicular. Underwater, the rope will simply float straight up automatically, pointing towards the surface, overcoming water resistance or currents

None of that is actually in the rules, though; that looks to be something made up by an AI tool. Whether the spell works the way you want it to underwater is a question for your DM.

"Attacks cannot pass into or out of the space." So does that mean that a creature can pass effortlessly through the portal, but if I try to shoot an arrow through an invisible force just stops it? But I can pass an arrow through, using my hand, if I don't have hostile intent? This seems like it could be exploited somehow...
On an unrelated note, I realized you could make a pretty stupid trap with this. You could cast this spell using a really long rope. Then you climb up it and fill the space up with rocks, arrows, etc. Then you pull the rope out. When your enemy passes under it, you end the spell, causing whatever you put in to fall down on them. It's a completely invisible trap that takes 10 minutes of setup and can be placed anywhere. Unfortunately, it lasts an hour max...

Yes, that's correct.

That does seem possible, though it also seems like something you could probably achieve with just a sturdy net.
