Sorry to hear the gameplay didn't come through - but the foundations (no pun intended) are definitely there! The environment is pretty solid - what did you have in mind for the game that'd be set here?

I didn't get around to fully fleshing out the details of the gameplay, but in broad terms I wanted to have a story where the building had been used for different worship throughout the ages. The old gods that used to be worshipped were sealed in the top tower of the building, and freeing them would reveal more details in the architecture itself (such as revealing statues of the old gods in the pillars etc.)
