Devil Jam is an independent production that stages a concert built around rhythm and automatic attacks. What we have here is a roguelite with some interesting ideas, based on upgrades placed on a dedicated grid to create an offensive and defensive score capable of wiping out entire armies of demons. What you end up with is a bold production that presents an overall functional combat system, but one that may feel rather repetitive even to those who strongly enjoy the genre. The presence of only a single map and a handful of bosses doesn’t help either, making the experience feel less deep than expected. However, the ticket price for Devil Jam is very low (€7.99), and it would almost be outrageous not to attend at least once this concert with decidedly hellish notes.
