A Zachtronics puzzle game in which you work as a reactor engineer, building factories that turn raw materials into chemical products.
How you code
Inside each reactor you lay out paths and instructions for two remotes called waldos, which pick up atoms, bond them and move molecules. This is visual programming: you plan instructions in space instead of writing text, and both waldos run in parallel.
