First of all, great product and I can't wait to see more.
Navigating the temple, one of the first things that came to mind was, how do I interact with those statues? They look great and are all in hot poses not seen in the rooms.
Please consider future additions to bring the statues "to life". It seems like a lower threshold for work since animations could be done on stand alone basis wouldn't necessarily call for a full 20minute sequence. And for their voices, only moans would be needed because they're statues, not people! Finally this might be a good way to introduce futa content too.
Off topic, are the nipple chains seen in the trailer availabile anywhere in the betaor, are those saved for the full release?
