Idle & Incremental Lovers recommends Atomic Synthesis: [i] Gotta catch 'em all! Collecting elements of the periodic table turns out to be quite a relaxing experience in this pleasing to the eye idler. With the Codex, great way to learn things about chemistry! [/i] + Starts as a clicker (or rather a "mouse hover"), quickly becomes an idler. Another victory for the automation team! + The unlock allowing you to assemble elements into molecules to boost your upgrades is a cool way to refresh the experience. Gotta chase those isotopes, too! + Props to the (pretty responsive) dev who just today released an absolutely great patch with small fixes, little improvements and... wait for it... the Codex! + The Codex is the perfect way to learn more about chemistry. The codex reveals progressively more information the higher mastery tier the element is. - Would have liked to get some kind of ending after completing the full periodic table. *What do you call two isotopes out on a Friday night? Carbon dating.* Found this review helpful?

Are you insinuating that AI was not used to make the UI? Endless scrolling, expanding and what's-clickable-when felt bad. And why does Amplify-cost increase when a new element is unlocked? Hovering to collect felt good though.
