Paku Tanah Java has a multi-layered jumpscare. The tension and fear become euphoria that this film offers to the audience while sitting in the cinema. Not to mention the sound design which, according to the author, was worked on quite nicely. Throughout the film, the sound production is what really supports the development of the atmosphere. In other words, make the scene even scarier and ready to make the hairs of the audience shiver. Although it presents a pretty intense jumpscare, the appearance of demons in this film is not that scary, why? It is still safe to see with the naked eye.
Bravo to producer!!
