The story itself, which is only about an hour long, is fascinating and offers intriguing, dark atmospheres. The initial tutorial section introduces evil in an interesting way, but unfortunately the time management feels a bit like an unnecessary addition to the genre. I would have preferred to experience the title as a traditional, longer adventure game, but even as it is, Cult Vacui leaves a positive impression, thanks to the hand-drawn graphics and the interestingly handled subject matter.
