Neat mechanic, here. I like the sketchy art style, too. However, I think it’s held back somewhat by a lack of feedback. It took me a little bit to figure out even the timing for the first level, because sometimes clicking didn’t feel like it actually did anything. Some kind of sound effect, or better, a visual, for when you interact with objects could go a long way, I think.
Other than that, perhaps the difficulty progression could be touched up a bit; I had quite a bit of trouble with the first couple levels, but then eg. “Mechanic” I somehow managed on my first try. Good work overall on this, though!
