Perkcade puts a pixel loyalty game in your storefront. Eight maps follow the calendar: Halloween until 8 November, Black Friday from 9 November, Christmas from 1 December, each with its own boss. Shoppers jump, roll and stomp with one of up to ten characters and earn coins for how well they play, never by chance. Coins trade for the rewards you turn on: percent off, shipping, a fixed amount or a product, inside a budget the game never exceeds. The builder adds your name, colours and products.

• A pixel game of about a minute: jump, roll, stomp and beat the boss
• Eight maps across the year: rising zombies, exploding pumpkins, thrown snowballs
• Up to ten characters with their own skills, from a shield to a sleigh ride
• Your name, colours and products in the game, or a whole world from the AI
• Coins for skill, never chance, trade for rewards that stay inside your budget
