It's simple, very simple at that, but hey, this game has a very clear vision of what it wants to be, and from a design and mechanical perspective it achieves that vision with flying colours. Does it work and is it effective? In part. There is entertainment value, enough that it will keep you engaged for upwards of an hour at a time, however, there's no denying that this won't be the same indie sensation as say, Vampire Survivors. If you're even marginally curious about how such an unorthodox game performs in practice, I'd simply suggest checking it out, because with Berserk or Die you could either permanently add a game to your collection, or get half a pack of V-Bucks... I know what I'd prefer to do with my money.
