You have made a great progress. The old ones were good too, but i prefer your now crab

These are great updates! I really like the treasure chest! Maybe if you did end up keeping a single coin you could add something like ridges on the edge, or an unknown monarch's face? I don't think it'd have to be very detailed or anything but it could help with making it look fairly unique.

I think the old versions are quite cute too! If you don't want to remove them entirely you could put them at the original size somewhere else (I would suggest a book or cap, but I'm guessing that wouldn't work for the theme of the game) as a sort of easter egg?

Originally picking up the coin would grant you a single coin, but since I'm redoing the whole game I might change it to giving a variable amount of coins so thats why I changed to the coin bag.

Nice redesigns, but depending on what the coin / bag of money is for, it should probabably revert back to a more detailed coin, but talking pixelart: the improvements have been great, and keep up the good work.
