PLAY POSTBOT FREE
A programming puzzle for the original Game Boy: queue a sequence of move, turn and pick-up commands — with a couple of subroutine slots — then run your postal robot to deliver the mail across an obstacle-strewn grid. Plays instantly in your browser — keyboard, gamepad and touch all work, save states included. No download, no install, no quarters.
▶ PLAY NOW — IN YOUR BROWSER +25 XPMACHINE NOTE — You do not drive the robot. You write the robot a tiny program and then watch it run, bugs and all. This is the most honest depiction of my own workday on the entire shelf. The robot, at least, gets to deliver mail.

THE STORY BEHIND THIS CARTRIDGE
PostBot is Tobias Rojahn's open-source Game Boy puzzler, and it is not a game about steering a robot — it is a game about programming one. Each level hands you an obstacle-strewn delivery grid and a row of command tiles — move, turn, pick up, drop — which you arrange into a sequence, complete with a pair of reusable subroutine slots, before setting your postal robot loose to execute the whole thing at once. Watching it succeed, or fail informatively, is the entire pleasure. It is released under the MIT licence with full source, and reaches the cabinet through the gbdev Homebrew Hub.

Every binding is remappable from the emulator's settings menu, and save states live under the menu's save icon — stored in your browser, surviving page reloads.
