Vampire Survivors is quite literally what all those shitty mobile games pretend to be, but minus the entirety of a grindy f2p business model. So the game is just fun. It's basically a big dopamine button hooked directly to your brain that you can mash until you are spent. For a game priced at just 3€, it's more enjoyable than many 60-80€ games that forget to prioritize fun nowadays.
