The visuals and audio are really good. The concept is also creative. Personally, I wasn't a huge fan of the gameplay as I found it got very repetitive very quickly. The tutorial was also not very clear: it isn't clear when the tutorial ends, that you could go back to the statue room, or what the black candle is for (without reading the description). It also took me a bit of time to work out how to use the cauldron, as it is the only thing that isn't simply clicked.
The graphics are really solid though :)
