Whether it’s a PC monitor or a smartphone display, indie game-makers tend to thrive on smaller screens. But when Josh DeBonis and Nik Mikros worked up the idea for their co-operative strategy/platformer hybrid Killer Queen, they went really big. So big they had to make their own unique stand-up machine for it. But, don’t worry: you don’t need quarters.

Like Bennett Foddy’s Speed Chess—the crazy remix of the classic game made by the creator of maladroit 100m dash simulator QWOPKiller Queen debuted at the New York University Game Center’s No Quarter exhibition, which commissions new games from creators that get presented to a curious public. Killer Queen mashes up the layout and feel of Joust and Super Mario Brothers but complicates things letting you harvest, kill or snail-ride your way to victory. Yes, you get to ride a giant snail. Watch the video. It’ll explain things.
