The concept is fun, I love running my little shop! The inspection and cleaning minigames are fun. I'd love to see some more in the future. Maybe pouring over other items with magnifying glasses or something. You have a great foundation here.
Graphics get the job done. Not awful, not mind blowing. Could stand to get some juice like animation and variety.
No music or sfx. Totally understandable, we don't have much time. Still, can't give a good score for that part.
Gameboy Soul is here.
Quirkiness in spades. I think you have a real unique idea here and I'd love to see you build on it with even more.
Secondary theme interpretation is pretty good! Items are old, they are gold. Check and check!
