SpaceChem gog-1

SpaceChem is a design-based puzzle game where players build complex chemical synthesis reactors using programmable manipulators called 'waldos'. You design intricate production lines to transform raw materials into target compounds by managing atomic bonds and reaction cycles. Each puzzle presents unique challenges requiring optimization of reactor designs under constraints like throughput and symbol limits. The game features over fifty progressively difficult puzzles set in a sci-fi narrative where you work as a Reactor Engineer for SpaceChem, confronting moral dilemmas and uncovering a deeper mystery through story interludes between levels.
