Reminds me of doing bin runs on Motor Town!
I had a couple of issues though, one was that the UI doesn't scale to screen size so most of the important information was cut off for me. The other was that it wasn't super clear what the colors were sometimes since the color overlay would mix with the item's color and it could sometimes be difficult to see if an object was classed as yellow or green. You could do a solid color overlay or a little circle which appears next to each object with it's color. Oh and I did find the AOE pickup upgrade hard to use, I wasn't sure why it would activate sometimes and not others.
I think with a few different town layouts this would be a well rounded little game!
