Even if it made the level entirely obvious it would be much more fun seeing how it's done than blindly moving sliders.
@Don G Rowe - Spoiler: Hint If the levers are working out for you, is there something else that you can use?
Not a perfect level as I know some may complain that it may not be intuitive enough or the graphics are rather plain, but (as you and many others already know) I enjoy levels with surprises, particularly when they have intricate engineering embedded in them. I sure hope others find this level and give it the time it deserves to see what you've engineered! Spoiler: Suggestions 1. Actuating a mechanism is more consistent when B is used horizontally (as he doesn't compress in that axis); 2. Placing the draggable slider in the stone wall with a rail would have avoided any chance of B falling into it; 3. It would have been even more cool if B had to go through the big mechanism a second time to come out above the win block. That was the most fun part: watching him get pushed around through it. Thank you for your imagination and dedication to build something so sophisticated!
The mechanism is really nice, before going for the win I made sure to make B step on it for a second time just to see him interacting with the mechanism and fall from the top floor.
