3 Learn

Programming you can hold.

A variable is where the ship is. A condition is whether you caught the star. A function is what happens sixty times a second. Your first lesson ends with a game in your hand that wasn't there an hour ago.

Your first game

Nine small steps to a game where a ship collects stars. Each step shows the whole file and explains the new lines.

Friendly mistakes

“There is no picture called shipp. Did you mean images.ship?” Errors are written for the person who made them.

“How do I…”

38 short recipes: jump, keep score, a camera that follows, two players. Ordinary code you can read and change.

Show it off

Send your game to a friend's console nearby, and play it together.

4 Go deeper

Curious? It goes all the way down.

You never have to look under the hood. You're always allowed to.

• Write in C or WebAssembly when you want every last bit of speed.
• Games from other machines are translated as they play, so classic handheld games run at full speed on a chip that was never meant to run them.
• Every kind of game it plays is a file on the card. Add one and a new shelf appears in your library.
• Signed updates, so your console only runs system software from people you trust.
