Gave it another go! Got the tank nice and muddy and escaped! The rocks were a little janky holding onto them and trying to drop them on the spinning blades, its not quite clear whether I am inside the tank or outside the tank and some of the rocks got clipped into a oblivion so I dropped like 5 rocks to try and trigger the muddy water. I’m sure you had plans for some fish swimming around in there too, to really sell the "swimming" part of the experience. The movement is so good, with some fish swimming around it really would have sold that immersion.
