In his Vampire Survivors review , Matt Cox described the game as something he could play with "one hand in a packet of crisps". I think about this quite often, actually, as someone whose largely offline friends (or Fortnite/FIFA pals) ask me to recommend them a game that's good or interesting. Show them something popular like Elden Ring and, despite its grandeur, it might prove too much in all facets.
But Vampire Survivors? It's an easy sell: simple, digestible, ridiculous value. All of this is to say, One BTN Bosses is from the same school of the easy sell. You can fight bosses with one hand in a packet of pickled onion Space Raiders, after all.
The joy of One BTN Bosses is its simplicity. The story is good because it's largely non-existent: you're part of some corporate structure that's bad, a cutesy pixelated cat wants you to defeat your managerial overlords. You go about their destruction with one hand in a packet of Dorito's Chilli Heatwave and the other on the left click of your mouse.
For the main campaign, there's a series of progressively difficult scenarios, where boss checkpoints keep you from climbing further. And if you get stuck, there's a series of warp holes that whisk you off to a roguelike mode where you can earn extra Grind Points (more on this later) or just blow off some steam in a different format. The format is, at its most basic level, a circle.
You're a little ship that whizzes around the circle automatically and the boss is at its centre. As you whiz.
