Zero Page

Zero Page is a single-player survival horror puzzle game that dares you to survive the horror of solving puzzles by yourself in space. If that wasn’t horrifying enough, you’re also going to have to solve them on a deserted spaceship using the only piece of equipment that still works: a personal computer from 1981. But with a little bit of BASIC and a lot of high-stakes debugging, you might just live long enough to find out why you’re alone, why you’re in space, why you’re on a dying ship circling an unknown planet, and why that ship wants to kill you.Back to BASIC
Find out if you're smart enough to not die in space, armed only with a machine that struggles to count higher than 256 — a highly accurate recreation of a classic 1980s personal computer, complete with floppy discs and a joystick.A Game About Thinking (The Thinking Man's Shooting)
Put that laser gun back in your space pants. You’re going to have to program your way out of this problem, by writing code that actually physically changes your environment.Also a Game About Action (The Action Man’s Thinking)
You won’t just be sitting at an old computer — well, you will, but not fictionally. In addition to programming, you’ll also get your hands dirty resurrecting an ancient spacecraft — patching critical holes, pressing important buttons, and bringing systems back online so they can start keeping you alive again.
