The verdict

A beautiful, open-ended Zachtronics puzzler about building and optimizing alchemy machines, with huge replay value. Skip it if you hate fiddly editors, tiny 4K UI, or puzzles with no limits.

Great for

Players who love optimizing, tinkering with programmable machines, and chasing leaderboard stats

Main risk

The clunky instruction editor and lack of UI scaling can make solving feel like tedious work

What players love

Addictive optimization and leaderboards

What players complain about

Clunky editor lacking QoL features

Mentioned in ~1 in 3 negative reviews

“No copy or paste (edit: I see that you can select multiple instructions and drag them) No making snippets of code. No breakpoints. No way to stop and back the puzzle up a step.”
