Well, the videogame kind are definitely impossible, but if the gravitational field could travel through the portal then it would probably still conserve energy. The gravitational interactions around vertical portals would be exceptionally weird. If they were close enough, you’d probably experience weightlessness while in between them, but I can’t wrap my head around what would happen as they move further apart. That makes me hope someone tries to make a mod that models that in Portal…
The trick would be finding the tallest vertical line of sight you can. Just making portable plates and flying one would be hard to beat, but failing that maybe a mineshaft.
Make a drain hole at the bottom of a lake, that comes out above it. Put in a water wheel, free energy.
Never thought about it before, but I guess this makes portal guns impossible, since scenarios like this break conservation of energy.

But you know it’s possible from firsthand experience. Whomsth’n’t reached terminal velocity by shooting the ceiling & floor and jumping in?

Does it fire through water in the game?
There are no bodies of water but you can shoot through a falling stream of it.
No. The only water in the game is toxic (i.e. you die if you fall in) and you can’t fire the gun through it.
