Impressive mechanism. Working backwards is the key to success though it took me a while to know what needed to be done.
Very happy to see a new original idea from you my friend! Very interesting and unusual. I really love these unconventional ideas. In my opinion, there is only one problem - the poor visibility of the wheels inside (some of the wheels are covered with soot - a shadow, so it's hard to see). Thanks for your out of the box ideas! I love them very much. I wish you new inspiration! 5 from me! Even the most critical player has given you a 5 . This is a very valuable five
@ohmytian I think he just means you have high standards. He has to use a translator, so that can make it more difficult to communicate clearly.
