Fun game, but as others have pointed out, the sorter doesn't "work".
Unless it's not intended to put the eggs directly into the fuel station, but just near it. Because if that is the case, then it works fine.
I don't actually think you need to at this stage. It only automatically SORTS the stuff. It says nothing about fully funneling the stuff into the receptable.
If you make it fully automatic, there's kinda nothing left to do. I don't think you should make it full auto until you add more "layers/screens" or whatever the plan is.
