Quest Compiler

Write actual code — loops, conditionals and variables — to steer a hero through a dungeon as enemies tick closer.

How to play

Type a short program in a real code editor using move, turn and collect commands plus if/else, while loops and variables. Run it and watch the hero execute one statement at a time with a visible instruction pointer. Every action costs a tick — and the enemies advance on that same tick — so reach the exit efficiently. Clear every campaign level to win the day.

• Write code with move(), turn(left/right) and collect()
• Use if/else and while conditions on what's in front of the hero
• Declare and update variables to control loops
• Reach the exit, collecting gems, before the enemies catch you

Controls

• Desktop: type in the editor, then click Run, Step, Reset or Load Hint
• Phone & tablet: tap the editor to type and use the on-screen buttons; a physical keyboard is recommended for coding

Tips & strategy

• Use Step to watch the instruction pointer and catch exactly where your logic goes wrong
• A while loop reading 'front' lets one short program handle corridors of any length
• Fewer ticks mean fewer enemy moves — efficient code is also safer code

What you'll learn

Quest Compiler is a learn-to-code puzzle with a real mini-language of loops, conditionals and variables — a gentle first programming language.

• Skills: coding fundamentals, variables, loops, conditionals
• Best for: roughly grades 5–10 (ages 10–16)
• For parents & teachers: a real first programming language, gently introduced.
