I think I might be stuck in the water grid of Reborn. I spent quite some time fighting and puzzling my way through, up until I reached the room in where Taka hides himself behind a locked door, and you're supposed to open it. I think the "key" to the door is the one located on the platform you're standing in, but on the opposite side. I couldn't get there for the life of me, and then I realised that if the water levels rose up, I could.
However, there is no way of rasing the water levels while you are on the place to jump to that...the only scenario in which it was like that was when entering. So, did I just screw it up by not getting it when I entered the room? Or is there still a way to fix this?
