Love the theme! Music and the hook on the rail also makes sense thematically. Great tutorial and great idea, the only thing holding this back is are two things: the ability to move the arm forward and backward (could just use W and S so that mouse controls up/down/left/right), as well as having some core items be accidentally tossed into a completely inaccessible spot. I think you already have some invisible walls set up so probably just need a bit of refining there.
Oh and I got my hand stuck in the pot multiple times haha. But I had a great time nonetheless! I could only beat the first level - as soon as it got to the second and I had to cut ingredients and the knife flew off the table I gave up
