Very interesting concept, it's a lot of fun!
Unfortunately I could not figure out the lava room, but up until there the level design and dialogue were great.
Great job!

Thanks for playing!
In the lava room, lift and throw the small brown statues to the platforms then hookshot them to cross. Put a statue on the switch in the cave to lower the lava, then open the treasure chest that had been covered by lava and use the ability you get to wall jump out of the room via the shaft on the left side of the room.
