Dear Alchemists,

v0.4.3.4046 is now live! We have added Sandbox Mode in this update. You can select this mode when starting a new game.

In Sandbox Mode, all things are unlocked, and you can build without resources. We also added Input / Output Portal and Flask for testing production lines. This mode is perfect for Blueprint designers or players who want to play Alchemy Factory with no stress.

Additionally, this update includes some performance optimizations. We have adjusted our multithreading strategy by offloading more calculations to background threads. This improves FPS and smoothness of the Game Thread. Theoretically, players with large factories will see a better performance.

Chinese New Year is approaching, so we decided to take a short break. Please understand that responses on all social platforms may be delayed during the holiday. We wish everyone a Happy Chinese New Year and a prosperous Year of the Horse!

Meanwhile, Alchemy Factory will take part in the "Chinese New Year Sale 2026" on Steam. The discount will start on February 13th. Stay tuned!

Upcoming Plans:

More performance and QoL optimizations based on players' feedback.
Add more interesting structures and recipes.
Character Shrinking Machine, we are working on it.
