The game looks incredible.
The main issue I had was there are so many details and items that finding out what is actually an interactive item was overwhelming. Nothing really stood out in terms of items you could pick up. The only non-paper item I found was the lock pick
It turned into an experience of clicking on everything just in case it was a usable item.
I managed to get a few items but never found the a way to actually interact to solve anything (the lock pick needing something extra, trying to use a sheet of paper or the blueprint under the door didn't work).
I made it as far as looking for the animal companions, so looked at several of the paintings but couldn't interact with them besides noticing the ostrich painting was in a weird location and never figured out what the animal with the crown was supposed to be.
Ways to improve would be having more hints and making interactive items more prominent.
A lot of escape games either have fixed scenes you move between or just less items on the stage to make the purpose clearer. That would impact the visual aspect of Novelty negatively. I would just add a more robust hint system.
It does look great, though!
