I like the pixel art! There are only a couple things I would say, I would update the treasure picture a little. Also, this isn’t required, but updating the people’s pictures on the bottom to look more tuned in with the game might make them fit more. You could make the fonts the same too. I think that would make it look pretty good.
All in all, this game looks really good! Just a few minor changes would make this game stand out to anyone. Great job dude!
