Is it still worth playing?
A reactor engineer on a run of planets builds molecules: two waldos, red and blue, run along paths you lay on a grid, picking up atoms, turning them, bonding them and dropping the result. The puzzle in this 2011 game for Windows, the Mac and Linux, later on iOS and Android, is writing the two programs so the shipment comes out right, and then faster. Each level gives base elements to be assembled and disassembled into new molecules, and no chemistry is needed, since the emphasis is on the circuitry. Seven people made it on weekends for about 4,000 dollars, with Seattle's disused gas works as the inspiration. The two waldos still make the answer a program, and a program can always be made shorter.
