Requires an updated version of chrome, or å browser that supports ecmascript 6. The point of the game is, like the Antikythera mechanism (age 200bc), to perform mathematical calculations using mechanical components. This is my first LD entry, and I made it in just under 7 hours, because I arrived late to the party :)
I didn't have time to implement any puzzles or tutorials, so it's only a sandbox of mechanics, but I put some suggestions up for some mathemathical functions you could try to recreate (only one at a time ofc). You select one gear or more as an input gear (from the type drop down and click the meter then the gear), and it will start rotating. Then add an output gear. The first task is to create one which will double the rotation (by simply putting a gear 20 cogs next to one with 10, so the ration will be 2:1), so that the output gear rotates twice as fast as the input gear. (The output meter is only there to visualize the rotation)
