The objective is to cut the water off.
Yes, that is obviously the objective; no one is disputing that. ;o)
Usually, when a room floods it doesn't continuously pour in forever. There is an exhaust point most of time. And then eventually the water either recedes or is manually removed.
Ah, but water
does continuously pour in forever if water is
continuously draining into the room forever, and it is unmistakably clear in the upper room that the water is still pouring (and not simply trickling) and draining into the lower room. I see your point, however, but I'd never said that I thought the water level should be rising in the room with the gang, just that you should be seeing water pour into that room from the pipe in the ceiling.
They just didn't show all of the frames in between.
But they should have. If Amanita didn't want to show the added animation, then why did they bother adding the frames of animation in the upper room depicting a constant flow of water? They've even added frames of animation by showing the shower (fountain?) by the church running into an empty reservoir. Why not instead make it impossible to leave the upper room before shutting off the water? (Josef could just shake his head each time you instructed him to climb the ladder.)
And yeah, it probably sounds like I'm going waaay overboard here, but I don't mean to come across like I'm irritated. (I guess that's what happens when using only text.) ;o)
