The atmosphere and the scenery are pretty well made, but I couldn’t find a single key, unfortunately :c. I would’ve kept searching, but there were quite a few issues with the lights and some rooms were particularly dificult to navigate because of that.
I also had some problems with the frame rate. I thought that maybe it had to do with the browser, but I couldn’t test it as there isn’t a Windows version that I could use.
The mansion and its surroundings look really good, though. Great work with that!
