I can see why that would be annoying. But the water part is actually the "last" section more or less or near it.
I'm guessing why that is that hard and tedious. As it requires multiple of those big horse gems to open fully till the end.

The monsters have a patrol pattern until it sees a player. Got to learn their movements. [spoiler]The cabinets are safe spots if you are inside them with doors closed. Is what we gathered from testing and the hint of the cabinet at the very first room.[/spoiler]

Thankfully though the map has a lot of shortcuts you can unlock as you slowly finish it. Quite tight in it's game design.
