This is really cool! I personally found the controls a bit cumbersome, so I didn't end up getting too far, but its a really cool concept. I'm not color blind, but even so I did have a bit of trouble telling apart the products so maybe there would be a way to better differentiate them.
PS. To elaborate on the controls, it's a bit hard to translate what you want to do into actions. So I keep wanting to drag over multiple squares, but it stops at one. And then the products themselves can get in the way of my interactions because the game can register me clicking on them when I mean to be clicking on the conveyor belt below.
