Looks like a weaving machine from the age of the Industrial Revolution. And throwing a “spanner” into the workings gives a satisfying 5 tap win.
My dear friend! I'm very glad you fixed the shortcut! Thank you very much for this! It will be my great pleasure to leave my comment again: Welcome to the forum. Very cool first level! Excellent mechanism! Interesting and thoughtful way for B, very good gameplay! Very neat and symmetrical design! Definitely a 5 from me! And a big plus for fixing the shortcut. Well done!
