Based on a little-known indie PC game by the same name, O$P$ (Owe Money Pay Money) tells the tale of Big Chief, a pro hoodie-wearer. He's tired of getting shortchanged and socially distanced by his errant clients, and decides it's time to get paid... in full!

Set in the renegade state of Shiokmenistan - formerly super rich Singapore - Big Chief takes on baddies of every shape and size, as he claws back what's owed to him... and then some! It's a classic platformer in the vein of Metroidvania games of old, with an Angry Birds twist to its gameplay.
