Ok, so I'm currently in the process of building my very own water temple, filled with puzzled, riddles, treasures, challenges, agility tasks and specific items to complete the temple. I've only managed to do the entrance lobby atm, and it's turned out quite interesting.
The size is huge, I just hope there's going to be enough space/ water to complete the entire build and from viwing above, it forms the shape of a heart (the main boss is going underneath the lobby - aka the temples life source - if MC had bosses XD), a face also forms out of the structure O.o
I'll add more images when I get round to it
