bro why is it in different language

ok i read but is it supposed to be broken?

I know this is over 6months old though, but could you do a video or take some more pictures of all the different functions etc? As after running this through the schematicannon the gearshifts are all over the place and the large...spinning drillhead contraption does what? i think something is missing from the design as theirs a hole in the floor under it going nowhere. I assume the 'Lava' sign you put there means im to fill the whole bottom of that area with lava? if so thats fine but to do what? Thankyou for any advice!
