Bought this, played it. Definitely worth it too.
The art is amazing, the voice acting is hot, the futa part of the game is good and Reimu is cute and lewd as always.
Should have had armpit play though... since it's Reimu.
The other game from this circle is also very good, has more futa than this and i also recommend it.
Anyways, the downside is that, like most other japanese games of this style, it get boring after you play through the major chunck of content, after some time the scenes are basically the same and the only change is a slightly different Reimu personality.
The game is good for a quick nut if nothing else though.
