Yes. It's an engineering game that can def put you in flow and disrupt your sleep and self control.

If you know space chem.or zachtronics, well, it's a zachtronics game.

If not: You are an alchemist, which means you use these tiny arms and other tools to assemble molecules. Just assembling something automatically is an accomplishment, but many aim to optimize the amount of space used, the speed at which molecules are constructed, and/or the cost of the machine itself.

Hubs says yes he bought it the 18th and has 24h playtime on steam and that it is by the same developer as "Space Chem."

Personally I'm enjoying Breakout 71 from F-Droid.

Basically you perform “alchemy” by designing machines to assemble molecule-like structures. The only requirement to progress is that the target molecule gets produced, but you get scored based on how efficient your machine is.
