Its a mixed bag that, on average, comes out on the better end of the scale.

The core mystery and mechanics behind it are both excellent and the main draw of the entire experience. Unfortunately, the actual way in which the mystery is told and presented is a bit more lacking. Long, dense blocks of text seem to be the main way that the reader is actually caught up to speed which can often make it a bit of a headache to get through everything. While a generous search feature and notes can ease the problem a bit, there is still a lot of information here that will be difficult to keep in your head all at once.

If you have the attention span, memory, and willingness to really sink your teeth into it, I think Sekimeiya definitely offers enough to make that effort worth it. But it really doesn't like making things easy on you.
