Send instructions to a robot. Try to reach the end of each level.

Controls

This game uses not just the standard PICO-8 controls of ⬆️⬇️⬅️➡️⭕❌ but also the whole keyboard for text input.

• Hold ⬆️ to show grid
• Press ⭕ (defaults to Z key) to start inputting instructions, and Enter to confirm them
• Press ❌ (defaults to X key) to restart level

Instruction set

• ^v<> move in that direction
  • You can use WASD as shortcuts to type these, when not inputting a variable name
• J> jump (to the right, in this case)
• $abc=1 set variable abc to 1 (variables default to 0)
• Built-in variables:
  • key true if you have a key
  • wall true if you're touching a wall
• ?COND:CODE or !COND:CODE evaluates all of CODE if COND is truthy (for ?) or falsy (for !)
  • Must be followed by a semicolon, another condition (they can't be nested), or the end of the code
  • Examples:
    • ?abc=2:^; if variable abc is equal to 2, move up
    • ?abc:^; if variable abc is truthy (non-zero), move up
    • !abc:^; if variable abc is falsy (zero), move up
  • Supports =, !=, <, <=, >, >=
• #0...L0 (replace 0 with any digit) loop
  • The #0 defines an anchor named 0
  • The L0 jumps execution back to the anchor 0
  • Hint: you can put L0 inside a conditional to conditionally repeat the loop
• If you encounter any errors (particularly when using conditionals), try adding a semicolon at the end, to separate it from the next statement. Sorry about that.
