A minor text update by me.

[Googolplex]

It feels more immersion breaking for your player to acknowledge the left mouse button than the omniscient text doing so.

Yes, because a mouse button only exists in a game. This is why hints are generally breaking the immersion and I always let them disabled. But for players who play with enabled hints, it is bad for the immersion and the new text can a bit help to avoid the feeling to get hints by the computer. Rather it looks like Penumbra where the player make his own thoughts and this is the best solution to obtain the most of atmosphere when having hints enabled.

Not only to acknowledge to press a key is breaking the immersion, even when the text said "You" is one of the no-go's. That feels like I'm just playing the game instead to be in there.

So it does not look as much like to play a computer game.
It looks more believable.
