Every planet is scattered with resources, and your goal is to collect them all. You don't move a single robot yourself. You write Python to automate them, then watch them work. Once everything's gathered and the spaceship is loaded, you're off to the next planet.

Dozens of resources, each its own puzzle

A tree you just harvest. A crate you push to the ship. A pyramid you circle around. Figure out what each one wants, then write the code to pull it off.

Write Python

You write Python right inside the game. It's one of the most popular programming languages, used everywhere from web apps to data science. The built-in code editor has syntax highlighting, autocomplete, and error detection. It's powered by the same technology as VS Code.

Beginner-friendly, with room to grow

No experience required. A built-in manual teaches you Python from the very first line, explaining every command and resource, so beginners are never lost. Hints are there when you're stuck. The later planets still get tricky enough to satisfy seasoned programmers. Push further and you can write smarter, more general code that solves entire puzzles on its own.
