Great interpretation of the theme, and nice mechanics. A bit hard for the right arm, maybe. ;)
This game would definitely deserve better audio.

Congrats!

Nice !
Good idea and fits well to the theme.
At first I could not understand the controls, it great that you've added these icons but that screw thing in the right hand felt too vague to mean the expected action (maybe a dial?)
It felt pleasing, especially with the crank sound once I figured in out.

It gets harder on higher platforms as you loose track of where you character is, maybe you've implemented that and I could get far enough but the camera could raise to follow the action.

Although I could pass the fourth level, it made me want to see the puzzles you designed.
It got too challenging for me as I could not find the restart level button.
I really miss one, having to restart the whole game when you fall is very frustrating.

I could not really wrap my head around the exact behaviour of the character as it felt going backwards without input sometimes.
The character's inertia makes it more difficult.

Anyway congrats !
Well done, I'll be sure to play it some more it there's no need to start over everytime !
