I really like this game.

It's a design-based puzzle, which means there is an infinite number of solutions to every puzzle. It has a lot in common with games that allow you to automate things, but the scale is much smaller and the context is breaking apart and fusing together chemical elements while moving them around the screen.

There is even a background story to this whole thing. You're a newly hired junior reaction engineer working for the Space Chem corporation. Your new career will bring you to distant planets where your task is to harvest and re-assemble valuable chemicals to send back home. But there have been rumors of accidents, and not everything is as it seems. I haven't uncovered the entire story, but I've found it interesting and mysterious so far. One caveat is that it's delivered solely through text and the occasional small illustration, which I personally don't mind, but others might.
