Nice work, this game turned out to be much more complex than it looks at first. I like the simplicity of the graphics and the use of color schemes to mark different locations. The ending where there's a chain of tasks to complete the game is well done, it makes searching around the grocery store fun. The signage also helps there.
I played through three times and was not able to get the ball for the kid at the end. I'm not sure what I missed. One thing that would be helpful is to be able to leave the room with the family at the end before talking to them, I went in there by accident a couple of times but then you're stuck and have to start over.
Another challenging part was finding the grocery store, the exit from the level with the sign to the entrance of the grocery store seems hidden in the level. My first play I thought maybe it was just unfinished, but I walked back and forth across the entire level just to make sure and eventually found it.
