I think the idea has potential, but it needs a lot more polish. I think make it a lot more clear when you've clicked on the item you're looking for - maybe add a sound effect or change the hue of the object. My team mate mentioned as well that you can just keep picking the same item and click it over and over to gain points. Maybe have it so its removed from the list once its found.
I think pixel art is a good choice for this game. The shelves and the items look fine, but their colours clash with the grey floor. I can also see lines on the floor, probably the edge of the sprite tiles. I think make the floor a cozier colour, like a light pink. The player's animation also could be improved, as right now only his legs are animated. You could make his head bob up and down, it would look a lot more appealing. I think the lo-fi music fits the relaxing atmosphere you're going for.
