The Clockwork Automaton
If you like games where one player sees the puzzle and the other holds the manual, The Clockwork Automaton is built the same way, for two people or for one person and an AI.
One of you looks at the automaton in the browser. The other opens the maker's notebook on a phone or prints it. Neither of you can solve a module alone.

It works over any call without sharing a screen. Share the round number from the start screen and you can both replay the exact same automaton later.
The face, the gear train, the masks, the chimes and the hallmarks. Four difficulty levels. Runs offline in your browser.
