Stuck at last chapter

[TeeKayOne2009]

Hello.

I am playing the game on my PS4. I am near the end because I ve got 16 of 18 totems.

But I dont know what to do now. I ve raised the water once and then there is a room which opens after beating a few enemies. There is only a chest?

How do I get the water one step higher to pass it? Thanks.

Hey, idk if you still need help on this since this was posted months ago but I did this level today and was stuck there for a moment as well. Theres a cracked wall in that room with the chest thats not in an obvious spot you need to bomb to get to the next lever
